10x+20=-50y
Subtract 50y from both sides. Anything subtracted from zero gives its negation.
10x=-50y-20
Subtract 20 from both sides.
\frac{10x}{10}=\frac{-50y-20}{10}
Divide both sides by 10.
x=\frac{-50y-20}{10}
Dividing by 10 undoes the multiplication by 10.
x=-5y-2
Divide -50y-20 by 10.
50y+20=-10x
Subtract 10x from both sides. Anything subtracted from zero gives its negation.
50y=-10x-20
Subtract 20 from both sides.
\frac{50y}{50}=\frac{-10x-20}{50}
Divide both sides by 50.
y=\frac{-10x-20}{50}
Dividing by 50 undoes the multiplication by 50.
y=\frac{-x-2}{5}
Divide -10x-20 by 50.
