c=0
Consider the second equation. Swap sides so that all variable terms are on the left hand side.
3=9a+30+0
Consider the first equation. Insert the known values of variables into the equation.
3=9a+30
Add 30 and 0 to get 30.
9a+30=3
Swap sides so that all variable terms are on the left hand side.
9a=3-30
Subtract 30 from both sides.
9a=-27
Subtract 30 from 3 to get -27.
a=\frac{-27}{9}
Divide both sides by 9.
a=-3
Divide -27 by 9 to get -3.
a=-3 c=0
The system is now solved.
