The answer is going to be x=28

Here is how I did it:

You first need to subtract it first
6x/7+15-8=31

6x/7+7=31

you have to find the common denominator

6x/7+7=31

6x/7+7*7/7=31

Multiply all the terms by the same value to eliminate fraction denominators

7(6x+49)/7=7*31

6x+49=7*31

Multiply the numbers

6x+49=7*31

6x+49=217

Subtract 49 from both sides

6x+49=217
-49 -49

Now theres 6x=168

Divide both sides

6x=168
—- —-
6 6

Simplify

x=28 is your answer
