Step-by-step explanation:
Try using either the app the calculater not like those other ones this calculator can solve fractions and almost any other thing
The average salary is $18,725
To find the answer add up each job's salary then divide by the number of jobs.
28,700 + 18,600 + 14,66 + 13,00 = 74,900
Then divide 74,900 by 4 ( added 4 numbers )
Answer:
The step 4 is not what he should have done. But the wrong is step 5, because if he added -2x both sides, it would give the following equation:

and not 
Note that in step 4 he should have added 2x and not -2x to both sides, but we still have the equality. The problem is that step 5 is totally wrong.
I don't know what answer is expected to this question, but I would mark step 5, because this is mathematically wrong.
Solving the equation

Using distribution

Add
both sides


Add 12 both sides

Divide both sides by 5
