9-3x+1=3x-4+13-7x
Combine -4x and 1x to get -3x.
10-3x=3x-4+13-7x
Add 9 and 1 to get 10.
10-3x=3x+9-7x
Add -4 and 13 to get 9.
10-3x=-4x+9
Combine 3x and -7x to get -4x.
10-3x+4x=9
Add 4x to both sides.
10+x=9
Combine -3x and 4x to get x.
x=9-10
Subtract 10 from both sides.
x=-1
Subtract 10 from 9 to get -1.
