10x=15+15y
Add 15y to both sides.
10x=15y+15
The equation is in standard form.
\frac{10x}{10}=\frac{15y+15}{10}
Divide both sides by 10.
x=\frac{15y+15}{10}
Dividing by 10 undoes the multiplication by 10.
x=\frac{3y+3}{2}
Divide 15+15y by 10.
-15y=15-10x
Subtract 10x from both sides.
\frac{-15y}{-15}=\frac{15-10x}{-15}
Divide both sides by -15.
y=\frac{15-10x}{-15}
Dividing by -15 undoes the multiplication by -15.
y=\frac{2x}{3}-1
Divide 15-10x by -15.
