what is the answer to A/3+A/3-1=A

Question

I cant figure this equation out.  Its suppose to be A over 3

Answer 1

A/3 + A/3 - 1 = A     Combine the first two terms

2A/3 - 1 = A            Multiply both sides by 3 to eliminate the denominator

2A - 3 = 3A              Subtract 2A from both sides

- 3 = A
