Answer:x=-9
Explanation:
Add 12 to both sides: 4x - 12 = 8x + 24
4x - 12 + 12= 8x + 24 + 12
Simplify: 4x - 12 + 12= 8x + 24 + 12
4x= 8x + 24 + 12
Simplify: 4x= 8x + 24 + 12
4x= 8x + 36
Subtract 8x from both sides: 4x= 8x + 36
4x-8x=8x+36-8x
Combine like terms: 4x-8x=8x+36-8x
-4x+ 8x + 36 - 8x
Combine like terms: -4x+ 8x + 36 - 8x
-4x = 36
Divide both sides by the same factor: -4x = 36
-4x/-4 = 36/-4
Simplify: -4x/-4 = 36/-4
x=36/-4
Divide the numbers: x=36/-4
x= -9
Answer: x= -9
