Answer:
the right answer is x+1
Step-by-step explanation:
1/2x+1
therefore :
2×1/2x+1
x+1
So for this, we will be applying the <u>zero product property</u>, which is <u>"if a x b = 0, then either a = 0 or b = 0 or both a and b = 0"</u>. In this case, a = x + 13 and b = x - 7. Solve them separately:

<u>Your answer is x = -13 and 7.</u>
