+%28+5%2A7.7+%29%2Fx+=+%28+5+-+x+%29%2Fx+
+38.5%2Fx+=+%28+5-x+%29%2Fx+
If I do the division on the right side, I get:
+38.5%2Fx+=+-1+%2B+5%2Fx+
Multiply both sides by +x+
+38.5+=+-x+%2B+5+
+x+=+5+-+38.5+
+x+=+-33.5++
------------------
check:
+38.5%2F%28-33.5%29+=+%28+5+-%28-33.5%29+%29+%2F+%28-33.5%29+
Multiply both sides by +-33.5+
+38.5+=+5+%2B+33.5+
+38.5+=+38.5+
OK

5(7.7)/x = 13.6 + (5 – x)/x
38.5/x = 13.6 + (5 – x)/x
Multiply by x to get: 38.5 = 13.6x + 5 – x
38.5 – 5 = 13.6x – x
33.5 = 12.6x
33.5/12.6 = x
x = 2.658730159
Any other answer is WRONG!!

Tutor teachmath got this one right, and even showed his work for once. But I think x=335/126 is a better answer than his decimal approximation.

The other tutor left out part of the original equation....
