3a=7+2
Consider the first equation. Add 2 to both sides.
3a=9
Add 7 and 2 to get 9.
a=\frac{9}{3}
Divide both sides by 3.
a=3
Divide 9 by 3 to get 3.
b=3
Consider the second equation. Insert the known values of variables into the equation.
c=3
Consider the third equation. Insert the known values of variables into the equation.
a=3 b=3 c=3
The system is now solved.
