so we see a right triangle. it is divided into two parts, one is "x" and the other part that adds with "x" must be "5-x," correct?

so how do we find what "x" is?

POSSIBLE SOLUTION ?:

1. set the equation to 3/x = 4/5-x

2. cross multiply

3. get 7x=15

4. divide 7 on each side

5. x = 15/7

is this correct?
