7x=15-15y
Subtract 15y from both sides.
\frac{7x}{7}=\frac{15-15y}{7}
Divide both sides by 7.
x=\frac{15-15y}{7}
Dividing by 7 undoes the multiplication by 7.
15y=15-7x
Subtract 7x from both sides.
\frac{15y}{15}=\frac{15-7x}{15}
Divide both sides by 15.
y=\frac{15-7x}{15}
Dividing by 15 undoes the multiplication by 15.
y=-\frac{7x}{15}+1
Divide 15-7x by 15.
