-x+12=45-3x+10x-1
Combine 2x and -3x to get -x.
-x+12=45+7x-1
Combine -3x and 10x to get 7x.
-x+12=44+7x
Subtract 1 from 45 to get 44.
-x+12-7x=44
Subtract 7x from both sides.
-8x+12=44
Combine -x and -7x to get -8x.
-8x=44-12
Subtract 12 from both sides.
-8x=32
Subtract 12 from 44 to get 32.
x=\frac{32}{-8}
Divide both sides by -8.
x=-4
Divide 32 by -8 to get -4.
