Answer:

2

Step-by-step explanation:

In algebra, you can replace the letters in an equation with whatever number they equal.

So because a = 2, we can replace the a in this formula with the number 2

We can do the same thing for the rest of these letters!

so...

a + b + c

becomes

2 + 1 + (-1)

now all we need to do is solve :)

2 + 1 + (-1)

3 + (-1)

3 - 1
