(5) less than the sum of (2x) and (3). Which is the correct expression?

Answer and explanation

Correct answer: \(2x+3-5\)

First, the sum of \(2x\) and \(3\) is \(2x+3\). “5 less than the sum” means subtracting 5 from this sum, so the correct expression is \(2x+3-5\). \(5-(2x+3)\) would mean subtracting the sum from 5, which represents a different statement. Exam tip: In “less than” phrases, identify the quantity from which subtraction is to be made.
