b=-5-3\times 5
Consider the third equation. Insert the known values of variables into the equation.
b=-5-15
Multiply -3 and 5 to get -15.
b=-20
Subtract 15 from -5 to get -20.
d=-20
Consider the fourth equation. Insert the known values of variables into the equation.
a=-5 c=5 b=-20 d=-20
The system is now solved.
