5x=100-10
Consider the second equation. Subtract 10 from both sides.
5x=90
Subtract 10 from 100 to get 90.
x=\frac{90}{5}
Divide both sides by 5.
x=18
Divide 90 by 5 to get 18.
18+y=13
Consider the first equation. Insert the known values of variables into the equation.
y=13-18
Subtract 18 from both sides.
y=-5
Subtract 18 from 13 to get -5.
x=18 y=-5
The system is now solved.
