7\left(-5\right)-2y=3
Consider the second equation. Insert the known values of variables into the equation.
-35-2y=3
Multiply 7 and -5 to get -35.
-2y=3+35
Add 35 to both sides.
-2y=38
Add 3 and 35 to get 38.
y=\frac{38}{-2}
Divide both sides by -2.
y=-19
Divide 38 by -2 to get -19.
x=-5 y=-19
The system is now solved.
