3 less than twice a certain number is equal to 2 more than 3 times the number
We can write: 2x - 3 = 3x + 2
So: -3 = x + 2
Solve: -5 = x
5 less than 5 times the number is
5 times the number = 5(-5) = -25
So, 5 less than 5 times the number = -25 - 5 = -30
Answer: A

2n - 3 = 2 + 3n
-5 = n
Thus, 5 less than 5 times the number is 5(-5) - 5 = -25 - 5 = -30.
