            One can read it as  %28x%2B2%29%2F%283x%29 + 2x - 15 = 106,


            or as               x+%2B+2%2F%283x%29+%2B+2x+-+15 = 106,


            or as               x+%2B+%282%2F3%29x+%2B+2x+-+15 = 106.


            As you, probably, understand, if the post admits different interpretation, it is not a Math problem, at all.


What is the numerator and what is the denominator in your formula  ?   ??

Use  PARENTHESES  to clearly show it  (!)

The part of the expression "2/3x" is ambiguous. According to standard rules for order of operations, it means %282%2F3%29x. However, many automated systems interpret it as 2%2F%283x%29.

Use parentheses where required; the equation you undoubtedly mean is

x+%2B+%282%2F3%29x+%2B+2x+-15+=+106

With that equation we can solve it using basic algebra.

Probably start by multiplying everything by 3 to get rid of the fractions....

3x%2B2x%2B6x-45+=+318
11x+=+363
x+=+33

ANSWER: x = 33
