a-5-4a=10
Consider the first equation. Insert the known values of variables into the equation.
-3a-5=10
Combine a and -4a to get -3a.
-3a=10+5
Add 5 to both sides.
-3a=15
Add 10 and 5 to get 15.
a=\frac{15}{-3}
Divide both sides by -3.
a=-5
Divide 15 by -3 to get -5.
a=-5 b=4
The system is now solved.
