Which expression represents (6) less than the sum of (x) and (y)?
Answer and explanation
Correct answer: \(x+y-6\)
The sum of \(x\) and \(y\) is \(x+y\). Taking 6 less than this sum means subtracting 6 from it, giving \(x+y-6\). The expression \(x+y+6\) adds 6, whereas the question asks for 6 less. Exam tip: For “less than” in this form, subtract the stated number from the expression already formed.
