3x-3=7-5y
Subtract 5y from both sides.
3x=7-5y+3
Add 3 to both sides.
3x=10-5y
Add 7 and 3 to get 10.
\frac{3x}{3}=\frac{10-5y}{3}
Divide both sides by 3.
x=\frac{10-5y}{3}
Dividing by 3 undoes the multiplication by 3.
5y-3=7-3x
Subtract 3x from both sides.
5y=7-3x+3
Add 3 to both sides.
5y=10-3x
Add 7 and 3 to get 10.
\frac{5y}{5}=\frac{10-3x}{5}
Divide both sides by 5.
y=\frac{10-3x}{5}
Dividing by 5 undoes the multiplication by 5.
y=-\frac{3x}{5}+2
Divide 10-3x by 5.
