a+5=3
Consider the first equation. Insert the known values of variables into the equation.
a=3-5
Subtract 5 from both sides.
a=-2
Subtract 5 from 3 to get -2.
c=-2
Consider the third equation. Insert the known values of variables into the equation.
d=-2
Consider the fourth equation. Insert the known values of variables into the equation.
a=-2 b=5 c=-2 d=-2
The system is now solved.
