Answer 1

HOW DO I SOLVE:   A=10; B=20; C=25;  IF A=B, WHAT DOES A+B+C = ?

Your problem statement has conflicting values. You say that A = 10 and B = 20, then you want A and B to be equal. You have to decide whether both will be 10 or both will be 20. Until you state which it will be, there is no way to solve the problem.

Answer 2

HOW DO I SOLVE:   A=10; B=20; C=25;  IF A=B, WHAT DOES A+B+C = ?

Pursuing one possibility, taking the assignment A=B literally, we are setting the value of A to equal the value of B.
In that case, A becomes 20, so we now have A=20, B=20 and C= 25

A + B + C = 20 + 20 + 25 = 65
