Answer:
x=7
Step-by-step explanation:
-3(x-1)+8(x-3)=6x+7-5x
-3x+3+8x-24=6x+7-5x
5x-21=x+7
4x=28
-3(x-1) + 8(x-3) = 6x + 7 - 5x
Distribute
-3x +3 +8x -24 = 6x +7 -5x
Combine like terms
5x -21 = x+7
Subtract x from each side
5x-x-21 = 7
4x -21 =7
Add 21 to each side
4x-21+21 = 7+21
4x = 28
4x/4 = 28/4
