-3x+3+4=6\left(x-1\right)-5
Use the distributive property to multiply -3 by x-1.
-3x+7=6\left(x-1\right)-5
Add 3 and 4 to get 7.
-3x+7=6x-6-5
Use the distributive property to multiply 6 by x-1.
-3x+7=6x-11
Subtract 5 from -6 to get -11.
-3x+7-6x=-11
Subtract 6x from both sides.
-9x+7=-11
Combine -3x and -6x to get -9x.
-9x=-11-7
Subtract 7 from both sides.
-9x=-18
Subtract 7 from -11 to get -18.
x=\frac{-18}{-9}
Divide both sides by -9.
x=2
Divide -18 by -9 to get 2.
