Solve 7%2F3+=+5%2Fx+%2B4 for x.

7%2F3+=+5%2Fx+%2B4

7%2F3+-4+=+5%2Fx

-5%2F3=+5%2Fx
multiply equation by 3x

-5x = 15
divide by -5
x=-3

.

    7%2F3 = 5%2Fx+%2B4  implies

    7%2F3+-+4 = 5%2Fx

    7%2F3+-+12%2F3 = 5%2Fx

    %287-12%29%2F3 =5%2Fx

    -5%2F3 = 5%2Fx


Cancel common factor 5 in both sides  (in other words, divide both sides by 5)

    -1%2F3 = 1%2Fx


From this proportion,  x = -3.    ANSWER

Solved.
