3x+2y=138+4
The opposite of -4 is 4.
3x+2y=142
Add 138 and 4 to get 142.
3x=142-2y
Subtract 2y from both sides.
\frac{3x}{3}=\frac{142-2y}{3}
Divide both sides by 3.
x=\frac{142-2y}{3}
Dividing by 3 undoes the multiplication by 3.
3x+2y=138+4
The opposite of -4 is 4.
3x+2y=142
Add 138 and 4 to get 142.
2y=142-3x
Subtract 3x from both sides.
\frac{2y}{2}=\frac{142-3x}{2}
Divide both sides by 2.
y=\frac{142-3x}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{3x}{2}+71
Divide 142-3x by 2.
