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
