In order to solve for x in the equation 7x + 15 = 38, you must first subtract 15 from both sides.
7x + 15 = 38
7x + 15 - 15 = 38 - 15
7x = 23
Then you must divide so there is only 1x = a number. This can be done by dividing both sides by 7.
7x = 23
7x / 7 = 23 / 7
x ≈ 3.286
So the solution for x in the equation 7x + 15 = 38 is x ≈ 3.286.
Hope this helps!
