15/a = 20/a + 12
Multiply each side by 'a' . . . 15 = 20 + 12a
Subtract 20 from each side . . . -5 = 12a
Divide each side by 12 . . . a = -(5/12)
=================================
This is kind of a weird result. The math questions posted here typically
work out to simple integer solutions.
We know that parentheses don't survive the process when a question is posted.
I wonder if the right side of the equation was supposed to be 20/(a+12) instead.
Let's try it:
15/a = 20/(a+12)
Multiply each side by a·(a+12) . . . 15(a+12) = 20a
Expand the left side . . . 15a + 180 = 20a
Subtract 15a from each side . . . 180 = 5a
Divide each side by 5 . . . a = 36
That was probably the question.
