Answer:
x = 16
Step-by-step explanation:
Since the lines are ||, the angles are each the same. This means that the equation has to look like this:
7x + 9 = 9x - 23
From there even out the sides, subtracting/ adding to one side what you do to the other:
7x +9 = 9x -23
-7x +23 -7x +23
0 32 = 2x 0
32 = 2x
Then divide each side by 2
Your answer is x = 16
