OpenStudy (lgbasallote):

mulltiply both sides by x..that will bring your x to the numerator..then multiply both sides by the inverse...you know how that is?

7/5 You can cross multiply giving you 7=5x. Divide by 5 and you get 7/5

OpenStudy (anonymous):

would 5/7 be correct too

OpenStudy (anonymous):

No, since when you divide by a fraction you multiply by the reciprocal. The reciprocal of 5/7 would be 7/5 as your answer.

OpenStudy (anonymous):

the only answers there are is 1 2/5 , 3/7 and 5/7

OpenStudy (anonymous):

1 and 2/5 is equal to 7/5, so 1 2/5 is the correct answer.
