x=\frac{3}{3}
Consider the second equation. Divide both sides by 3.
x=1
Divide 3 by 3 to get 1.
3\times 1+y=5
Consider the first equation. Insert the known values of variables into the equation.
3+y=5
Multiply 3 and 1 to get 3.
y=5-3
Subtract 3 from both sides.
y=2
Subtract 3 from 5 to get 2.
x=1 y=2
The system is now solved.
