His mistake is that he does not open the bracket first. The value of the x is negative of 4.
What is a BODMAS rule?BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Andre tried to solve the equation 1/4 ( x + 12 ) = 2.
First, open the bracket, then we have
[tex]\dfrac{x}{4} + \dfrac{12}{4} = 2[/tex]
On simplifying, we have
[tex]\dfrac{x}{4 } + 3 = 2[/tex]
Subtract 3 from both sides, we have
[tex]\dfrac{x}{4} = -1[/tex]
Multiply the equation by 4, we have
[tex]x = -4[/tex]
More about the BODMAS rule link is given below.

Peter placed an order with an online nursery for 6 apple trees and 5 azaleas and the order came to $147. The next order for 3 apple trees and 4 azaleas came to $96. What was the cost for each apple tree and for each azalea?
Answer:
$243
Step-by-step explanation:
The first order you made :
6 apple
5 azaleas
And total cast was:
$147
The secant order you order was:
3 apples
4 azaleas
And total cast was:
$96
The total cast of both orders is:
$243
The total cost for each apple tree and for each azalea is $243
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The first order you made are consistes of 6 apple and 5 azaleas
And total cost was $147
The second order you order was consistes of 3 apples and 4 azaleas
And total cost was $96
The total cost of both orders is;
147 + 96 = $243

Equations are always true
÷ and x always undo each other
that is an equation
Step-by-step explanation:
Write an equation for each line (use the picture)
Red Line:
Blue Line:
Green Line:
Yellow Line:
Answer:
Red Line: y=4
Blue Line: y=-2
Green Line: x=-1
Yellow Line: x=6
Step-by-step explanation:
Red line: the line crosses through 4 on the y axis. Therefore, y=4.
Blue line: the line crosses through -2 on the y axis. Therefore, y=-2.
Green line: the line crosses through -1 on the x axis. Therefore, x=-1.
Yellow line: the line crosses through 6 on the x axis. Therefore, x=6.
This is a bit confusing because when you see a horizontal line your mind might assume it would be an x=. Yet, it is the opposite. Hope this helps!

Hayley has $155 in savings, and her brother Hank has $230. Hayley is saving $10 each week, and her brother is spending $15 each week. After how many weeks will their savings accounts have the same amount of money in them?
What is the best way to set up this word problem to solve?
15x+155=230+10x
15 x plus 155 is equal to 230 plus 10 x
155−15x=10x+230
155 minus 15 x is equal to 10 x plus 230
155+10x=230−15x
155 plus 10 x is equal to 230 minus 15 x
155−10x=230+15x

Answer:
The Correct Answer is The 3rd one, Or C
Step-by-step explanation:
It will take 3 weeks
If its right mark me brainliest if its wrong report me.
Answer:
$155+$10x=$230-$15x
Step-by-step explanation:
weeks= x
$155+$10x=$230-$15x is the correct answer because hayley currently has $155 in her saving and you have to add the 10 dollars she saves each week which is 10x. On the other hand, her brother has $230 and spends $15 dollars every week so that is 15x.

Which equations demonstrate how to solve for x, and what is the value of x?
a The equation 52 + 90 + x = 180 deomnstrates one way to solve for y, and y = 38 degrees. Since x + y = 180, then x = 142 degrees.
b The equation 52 + 90 + x = 90 deomnstrates one way to solve for y, and y = 52 degrees. Since x + y = 180, then x = 128 degrees.
c The equation 52 + 90 + x = 180 deomnstrates one way to solve for x, and x = 38 degrees.
d The equation 52 + 90 + x = 90 deomnstrates one way to solve for x, and x = 52 degrees.
Answer:
A
Step-by-step explanation:
The first step is to find yAll triangles have interior angles that add together to measure 180 degreesSince we know this you can subtract the known angle values (90 and 52) from 180180-52-90= 38 38 is your yx is an exterior angle so y+x also equals 180in order to find x just take your y value and subtract it from 180180-38=142The equation 52 + 90 + x = 180 deomnstrates one way to solve for y,
and y = 38 degrees. Since x + y = 180, then x = 142 degrees.
Calculation to find out angles :the sum of interior angles in a triangle is always 180 degrees
Add all the interior angles and make it equal to 180 degrees
[tex]90+52+y=180\\142+y=180\\[/tex]
Subtract 142 from both sides
y=38 degrees
angle y is 38 degrees
Angles y and x are linear pair of angles , the sum of linear pair is 180 degrees
[tex]y+x=180\\38+x=180[/tex]
Subtract 38 from both sides
x=142 degrees
The equation 52 + 90 + x = 180 deomnstrates one way to solve for y, and y = 38 degrees. Since x + y = 180, then x = 142 degrees.
