Answer:

c-a=b

Explanation:

If a+b=c, then to prove my statement, we can assign random values to a and b:

a=3

b=8

a+b=11

3+8=11

11-3=8

that is correct! In other words, I used the process of elimination.

Hope this helps!

A + B = C

Answers:

So if you subtract A from C you will get B

C-A=B

If you subtract B from C you will get A

C-B=A

This is very important when it comes to finding the sides of triangles and unknown variables.
