# Impossible to Solve? (Easy)

Algebra Level pending

When solving systems of linear equations, we are taught that we need just as many equations as there are variables to solve the system. However, you don't need to have all the equations if you are solving for one variable.. Here's an easy system of two linear equations with three variables, yet you can solve one of the variables. Give it a try!

If $$2a+3b+2c=12-2a-b$$ and $$c=a+b$$, then $$c=$$
