-49 + -2x + 12x = 101 + -12x + 12x Combine like terms: -2x + 12x = 10x -49 + 10x ... 101 + 49 = 150 10x = 150 Divide each side by '10'. x = 15 Simplifying x = 15

10x - 15 = 12x - 101

Add 15 on both sides

10x = 12x - 86

Subtract 12 on both sides

-2x = -86

Divide -2 on both sides

x = 43

I hope this helps! :)
