Sample questions (3 of 16)

  1. Question 1

    Simplify 3x + 4y - x + 2y.

    • A) 2x + 6y
    • B) 4x + 6y
    • C) 2x + 2y
    • D) 3x + 6y
    Show answer

    Answer: 2x + 6y

    Group like terms separately. x terms: 3x - x = 2x. y terms: 4y + 2y = 6y. Combined: 2x + 6y.

  2. Question 2

    Simplify 5a + 2b - 3a + b.

    • A) 2a + 3b
    • B) 8a + 3b
    • C) 2a + b
    • D) 5a + 3b
    Show answer

    Answer: 2a + 3b

    Collect like terms: a-terms: 5a - 3a = 2a; b-terms: 2b + b = 3b. Result: 2a + 3b.

  3. Question 3

    Simplify 4(x + 2) - 3.

    • A) 4x + 5
    • B) 4x + 8
    • C) 4x - 1
    • D) 4x + 11
    Show answer

    Answer: 4x + 5

    Expand the bracket: 4 x (x + 2) = 4x + 8. Then subtract 3: 4x + 8 - 3 = 4x + 5.
