Answer:
x=3
Step-by-step explanation:
First we will distribute the 4 into the (x+7) and 9 into (x-1).
You should then got
4x+28=9x-9+22
Afterwards we combine like-terms
4x+28=9x+13
Then, we put all the alike values on the same side together.
4x+28=9x+13
-4x -4x
___________
28=5x+13
-13 -13
____________
15=5x
You then divide both sides by 5 to isolate x
15/5= 3
x=3
