8x=-x_{7}
Subtract x_{7} from both sides. Anything subtracted from zero gives its negation.
\frac{8x}{8}=-\frac{x_{7}}{8}
Divide both sides by 8.
x=-\frac{x_{7}}{8}
Dividing by 8 undoes the multiplication by 8.
x_{7}=-8x
Subtract 8x from both sides. Anything subtracted from zero gives its negation.
