5x=9-4
Consider the first equation. Subtract 4 from both sides.
5x=5
Subtract 4 from 9 to get 5.
x=\frac{5}{5}
Divide both sides by 5.
x=1
Divide 5 by 5 to get 1.
1+9y=3
Consider the second equation. Insert the known values of variables into the equation.
9y=3-1
Subtract 1 from both sides.
9y=2
Subtract 1 from 3 to get 2.
y=\frac{2}{9}
Divide both sides by 9.
x=1 y=\frac{2}{9}
The system is now solved.
