Distribute.
3(x+6)
3x+18
8(x-3)
8x-24
3x+18+8x-24
Combine like terms.
11x-6= 27
Add 6 to the other side.
11x= 33
Divide both sides by 11.
x=3
I hope this helps!

Answer:
<u>A) 2¹²</u>
Step-by-step explanation:
Given :
Equate the equation to y :
- 3x - y + y = 12 + y
- 12 + y = 3x
- 12 + y - 12 = 3x - 12
- <u>y = 3x - 12</u>
<u />
Substituting in the expression :
