-x-10=-x_{4}
Subtract x_{4} from both sides. Anything subtracted from zero gives its negation.
-x=-x_{4}+10
Add 10 to both sides.
-x=10-x_{4}
The equation is in standard form.
\frac{-x}{-1}=\frac{10-x_{4}}{-1}
Divide both sides by -1.
x=\frac{10-x_{4}}{-1}
Dividing by -1 undoes the multiplication by -1.
x=x_{4}-10
Divide -x_{4}+10 by -1.
x_{4}-10=x
Add x to both sides. Anything plus zero gives itself.
x_{4}=x+10
Add 10 to both sides.
