1\frac{3}{8}138

Explanation:

2(-3x+4)-3x=7(x-1)-72(−3x+4)−3x=7(x−1)−7
You need to remove parentheses
-6x+8-3x=7x-7-7−6x+8−3x=7x−7−7
Then you need to collect like terms and calculate
-9x+8=7x-14−9x+8=7x−14
Move terms
-9x-7x=-14-8−9x−7x=−14−8
-16x=-22−16x=−22
Divide both sides by -16−16
x=\frac{22}{16}=\frac{11}{8}=1\frac{3}{8}x=2216=118=138
