Answer:
12
Step-by-step explanation:
Essentially, 60 and the 5 us must be equal:
60=5u
Divide both sides by 5 to solve for u but keep the equation balanced.
12=u
Factor both equations, you'll get (x-9)(x+1) for the first one and (x+1)(x-1) for the second one.
new equation: (x-9)(x+1) over (x+1)(x-1). You can cancel out both (x+1)s because when divided by each other you're left with the number one. The answer is (x-9) over (x-10
