978-3x=2x-12
Multiply both sides of the equation by 6, the least common multiple of 2,3.
978-3x-2x=-12
Subtract 2x from both sides.
978-5x=-12
Combine -3x and -2x to get -5x.
-5x=-12-978
Subtract 978 from both sides.
-5x=-990
Subtract 978 from -12 to get -990.
x=\frac{-990}{-5}
Divide both sides by -5.
x=198
Divide -990 by -5 to get 198.
