3x=10-y
The equation is in standard form.
\frac{3x}{3}=\frac{10-y}{3}
Divide both sides by 3.
x=\frac{10-y}{3}
Dividing by 3 undoes the multiplication by 3.
10-y=3x
Swap sides so that all variable terms are on the left hand side.
-y=3x-10
Subtract 10 from both sides.
\frac{-y}{-1}=\frac{3x-10}{-1}
Divide both sides by -1.
y=\frac{3x-10}{-1}
Dividing by -1 undoes the multiplication by -1.
y=10-3x
Divide 3x-10 by -1.
