15x+5-7=21x-4-7x-8
Combine 13x and 2x to get 15x.
15x-2=21x-4-7x-8
Subtract 7 from 5 to get -2.
15x-2=14x-4-8
Combine 21x and -7x to get 14x.
15x-2=14x-12
Subtract 8 from -4 to get -12.
15x-2-14x=-12
Subtract 14x from both sides.
x-2=-12
Combine 15x and -14x to get x.
x=-12+2
Add 2 to both sides.
x=-10
Add -12 and 2 to get -10.
