r=-2-\left(-3\right)
Consider the third equation. Insert the known values of variables into the equation.
r=-2+3
Multiply -1 and -3 to get 3.
r=1
Add -2 and 3 to get 1.
s=1
Consider the fourth equation. Insert the known values of variables into the equation.
p=-2 q=-3 r=1 s=1
The system is now solved.
