y=\frac{12}{3}
Consider the second equation. Divide both sides by 3.
y=4
Divide 12 by 3 to get 4.
4x-4=4
Consider the first equation. Insert the known values of variables into the equation.
4x=4+4
Add 4 to both sides.
4x=8
Add 4 and 4 to get 8.
x=\frac{8}{4}
Divide both sides by 4.
x=2
Divide 8 by 4 to get 2.
x=2 y=4
The system is now solved.
