10x=21-10y
Subtract 10y from both sides.
\frac{10x}{10}=\frac{21-10y}{10}
Divide both sides by 10.
x=\frac{21-10y}{10}
Dividing by 10 undoes the multiplication by 10.
x=\frac{21}{10}-y
Divide 21-10y by 10.
10y=21-10x
Subtract 10x from both sides.
\frac{10y}{10}=\frac{21-10x}{10}
Divide both sides by 10.
y=\frac{21-10x}{10}
Dividing by 10 undoes the multiplication by 10.
y=\frac{21}{10}-x
Divide 21-10x by 10.
