2x=5-3
Consider the first equation. Subtract 3 from both sides.
2x=2
Subtract 3 from 5 to get 2.
x=\frac{2}{2}
Divide both sides by 2.
x=1
Divide 2 by 2 to get 1.
1+2y=8
Consider the second equation. Insert the known values of variables into the equation.
2y=8-1
Subtract 1 from both sides.
2y=7
Subtract 1 from 8 to get 7.
y=\frac{7}{2}
Divide both sides by 2.
x=1 y=\frac{7}{2}
The system is now solved.
