6x=15-3y
Subtract 3y from both sides.
\frac{6x}{6}=\frac{15-3y}{6}
Divide both sides by 6.
x=\frac{15-3y}{6}
Dividing by 6 undoes the multiplication by 6.
x=\frac{5-y}{2}
Divide 15-3y by 6.
3y=15-6x
Subtract 6x from both sides.
\frac{3y}{3}=\frac{15-6x}{3}
Divide both sides by 3.
y=\frac{15-6x}{3}
Dividing by 3 undoes the multiplication by 3.
y=5-2x
Divide 15-6x by 3.
