18x=210-6y
Subtract 6y from both sides.
\frac{18x}{18}=\frac{210-6y}{18}
Divide both sides by 18.
x=\frac{210-6y}{18}
Dividing by 18 undoes the multiplication by 18.
x=\frac{35-y}{3}
Divide 210-6y by 18.
6y=210-18x
Subtract 18x from both sides.
\frac{6y}{6}=\frac{210-18x}{6}
Divide both sides by 6.
y=\frac{210-18x}{6}
Dividing by 6 undoes the multiplication by 6.
y=35-3x
Divide 210-18x by 6.
