3+3=5x+63+3x
Combine 2x and -2x to get 0.
6=5x+63+3x
Add 3 and 3 to get 6.
6=8x+63
Combine 5x and 3x to get 8x.
8x+63=6
Swap sides so that all variable terms are on the left hand side.
8x=6-63
Subtract 63 from both sides.
8x=-57
Subtract 63 from 6 to get -57.
x=\frac{-57}{8}
Divide both sides by 8.
x=-\frac{57}{8}
Fraction \frac{-57}{8} can be rewritten as -\frac{57}{8} by extracting the negative sign.
