3x=30-4y
Subtract 4y from both sides.
\frac{3x}{3}=\frac{30-4y}{3}
Divide both sides by 3.
x=\frac{30-4y}{3}
Dividing by 3 undoes the multiplication by 3.
x=-\frac{4y}{3}+10
Divide 30-4y by 3.
4y=30-3x
Subtract 3x from both sides.
\frac{4y}{4}=\frac{30-3x}{4}
Divide both sides by 4.
y=\frac{30-3x}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{3x}{4}+\frac{15}{2}
Divide 30-3x by 4.
