Which expression represents adding (x+y) to four times (3x-2y)?

Answer and explanation

Correct answer: \(4(3x-2y)+(x+y)\)

The phrase “adding \((x+y)\) to four times \((3x-2y)\)” means first multiply the complete expression \((3x-2y)\) by 4, and then add \((x+y)\). Hence, \(4(3x-2y)+(x+y)\) is correct. In option B, 4 multiplies the entire sum, so it represents a different expression. Exam tip: When a whole expression is multiplied, enclose it in brackets.
