Answer: x = 3
Explanation:
You want to isolate your variable, so first you would do the inverse of your constant, which is -4, and take that from both sides.
6x+4=22
6x=22-4
6x=18
Again, to isolate the variable, you must do the inverse of multiplication, which is to divide 6 from each side.
6x/6=x
18/6=3
x=3
