4x+392=-3x
Multiply both sides of the equation by 8, the least common multiple of 2,8.
4x+392+3x=0
Add 3x to both sides.
7x+392=0
Combine 4x and 3x to get 7x.
7x=-392
Subtract 392 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-392}{7}
Divide both sides by 7.
x=-56
Divide -392 by 7 to get -56.
