2y=4
Consider the first equation. Add 4 to both sides. Anything plus zero gives itself.
y=\frac{4}{2}
Divide both sides by 2.
y=2
Divide 4 by 2 to get 2.
3x=1
Consider the second equation. Add 1 to both sides. Anything plus zero gives itself.
x=\frac{1}{3}
Divide both sides by 3.
y=2 x=\frac{1}{3}
The system is now solved.
