c=3\left(-5\right)-5\times 2+8
Consider the third equation. Insert the known values of variables into the equation.
c=-15-10+8
Do the multiplications.
c=-25+8
Subtract 10 from -15 to get -25.
c=-17
Add -25 and 8 to get -17.
d=-17
Consider the fourth equation. Insert the known values of variables into the equation.
a=-5 b=2 c=-17 d=-17
The system is now solved.
