If a + b = 2, a + c = 7, and b + c = 9, find a + b + c.

Note that for this problem, you don't need to find the value of each variable individually, you just need to know the value of \(a + b + c \).

 

Adding all 3 equations together gives us: \(2(a+b+c) = 18\). Can you find the value of \(a + b + c \) from here?
