Answer:

x = 3

Explanation:

1) Combine like terms

6 - 2x = 5x - 9x + 12

6 - 2x = -4x + 12

2) Add 4x to both sides.

6 - 2x = -4x + 12

+4x +4x

6 - 2x = 12

3) flip the equation and subtract 6 from both sides.

2x + 6 = 12

-6 -6

2x = 6

4) Divide by 2 on both sides.

6/ 2 = 3

x = 3

Answer: 3

Explanation:

Rearrange terms: -2x + 6 = 5x - 9x + 12

Combine like terms: -2x + 6 = -4x + 12

Subtract from both sides: -2x = -4x + 6

since we now know -4x + 6 = -2x, 6 is equal to 2x. Divide by 2, x = 3
