-3a=15+5
Consider the first equation. Add 5 to both sides.
-3a=20
Add 15 and 5 to get 20.
a=-\frac{20}{3}
Divide both sides by -3.
-b=-2+12
Consider the second equation. Add 12 to both sides.
-b=10
Add -2 and 12 to get 10.
b=-10
Divide both sides by -1.
a=-\frac{20}{3} b=-10
The system is now solved.
