ex=15+y
Add y to both sides.
ex=y+15
The equation is in standard form.
\frac{ex}{e}=\frac{y+15}{e}
Divide both sides by e.
x=\frac{y+15}{e}
Dividing by e undoes the multiplication by e.
-y=15-ex
Subtract ex from both sides.
\frac{-y}{-1}=\frac{15-ex}{-1}
Divide both sides by -1.
y=\frac{15-ex}{-1}
Dividing by -1 undoes the multiplication by -1.
y=ex-15
Divide -ex+15 by -1.
