-2a=86-3y
Subtract 3y from both sides.
\frac{-2a}{-2}=\frac{86-3y}{-2}
Divide both sides by -2.
a=\frac{86-3y}{-2}
Dividing by -2 undoes the multiplication by -2.
a=\frac{3y}{2}-43
Divide 86-3y by -2.
3y=86+2a
Add 2a to both sides.
3y=2a+86
The equation is in standard form.
\frac{3y}{3}=\frac{2a+86}{3}
Divide both sides by 3.
y=\frac{2a+86}{3}
Dividing by 3 undoes the multiplication by 3.
