4x=90-6y
Subtract 6y from both sides.
\frac{4x}{4}=\frac{90-6y}{4}
Divide both sides by 4.
x=\frac{90-6y}{4}
Dividing by 4 undoes the multiplication by 4.
x=\frac{45-3y}{2}
Divide 90-6y by 4.
6y=90-4x
Subtract 4x from both sides.
\frac{6y}{6}=\frac{90-4x}{6}
Divide both sides by 6.
y=\frac{90-4x}{6}
Dividing by 6 undoes the multiplication by 6.
y=-\frac{2x}{3}+15
Divide 90-4x by 6.
