Words can be rewritten in formula as \(5n = 2n-3\) from which we get n = -1. Since, we want the value of "three less than twice n", we substitute n = -1 on the right-hand side to get -5.

5 times n is three less than twice n.
We can write: 5n = 2n - 3
Subtract 2n from both sides to get: 3n = -3
Solve: n = -1
What number is three less than twice n?
In other words, we want to find the value of 2n - 3
Replace n with -1 to get: 2(-1) - 3
Evaluate to get: -2 - 3 = -5
Answer: A
