20x+6=10y
Add 10y to both sides. Anything plus zero gives itself.
20x=10y-6
Subtract 6 from both sides.
\frac{20x}{20}=\frac{10y-6}{20}
Divide both sides by 20.
x=\frac{10y-6}{20}
Dividing by 20 undoes the multiplication by 20.
x=\frac{y}{2}-\frac{3}{10}
Divide 10y-6 by 20.
-10y+6=-20x
Subtract 20x from both sides. Anything subtracted from zero gives its negation.
-10y=-20x-6
Subtract 6 from both sides.
\frac{-10y}{-10}=\frac{-20x-6}{-10}
Divide both sides by -10.
y=\frac{-20x-6}{-10}
Dividing by -10 undoes the multiplication by -10.
y=2x+\frac{3}{5}
Divide -20x-6 by -10.
