2x+3=7-y
Subtract y from both sides.
2x=7-y-3
Subtract 3 from both sides.
2x=4-y
Subtract 3 from 7 to get 4.
\frac{2x}{2}=\frac{4-y}{2}
Divide both sides by 2.
x=\frac{4-y}{2}
Dividing by 2 undoes the multiplication by 2.
x=-\frac{y}{2}+2
Divide 4-y by 2.
y+3=7-2x
Subtract 2x from both sides.
y=7-2x-3
Subtract 3 from both sides.
y=4-2x
Subtract 3 from 7 to get 4.
