b=-3-12
Consider the first equation. Subtract 12 from both sides.
b=-15
Subtract 12 from -3 to get -15.
4k-15=0
Consider the second equation. Insert the known values of variables into the equation.
4k=15
Add 15 to both sides. Anything plus zero gives itself.
k=\frac{15}{4}
Divide both sides by 4.
b=-15 k=\frac{15}{4}
The system is now solved.
