You need to convert the English into maths. That is the main challenge:

%2816%2Bx%29%2F%2837%2Bx%29+=+5%2F8 and now cross-multiply, to give
8%2816%2Bx%29+=+5%2837%2Bx%29
128+8x = 185+5x
3x=57
x=57/3
--> x=19

CHECK!!! --> 16+19 is 35 and 37+19 is 56, so the fraction is then 35/56 which simplifies to 5/8, so correct.

Now you try the subtract version yourself.
