Hi there!
The answer to this question is x=6.78
Process:
On both sides of the equation, there is a number in front of a set of parenthesis. Here you need to perform distributive property.
To get: 4+(1/3)x= -48 + x
Then in order to solve for x, you minus (1/3)x on both sides to get (23/3)x
Next: you add 48 on both sides to get 52
now your equation should look like this: 52= (23/3)x
then you multiply 3/23 on both sides to get x=6.78
