To solve the equation 7x + 9 = 23, you want to isolate the variable (the "x" term), so you first need to subtract 9 from each side to get 7x = 14. Then, you want to get the "x" term by itself, so you need to divide both sides by 7.

This gives you the solution: x = 2.

So, the answer to the equation 7x + 9 = 23 is x = 2.
