-10\times 4-9y=-4
Consider the first equation. Insert the known values of variables into the equation.
-40-9y=-4
Multiply -10 and 4 to get -40.
-9y=-4+40
Add 40 to both sides.
-9y=36
Add -4 and 40 to get 36.
y=\frac{36}{-9}
Divide both sides by -9.
y=-4
Divide 36 by -9 to get -4.
x=4 y=-4
The system is now solved.
