  1. Simplify the expression 3(2x + 4) − 2(x − 1).

    Answer: 4x + 14

    Distribute: 6x + 12 − 2x + 2 = 4x + 14.

  2. If 5y − 3 = 2y + 9, what is the value of y?

    Answer: 4

    5y − 2y = 9 + 3, so 3y = 12, giving y = 4.

  3. Which of the following is a binomial?

    Answer: 3x + 7

    A binomial has exactly two terms; 3x + 7 has two terms.

  4. Evaluate 2a² − 3b when a = 3 and b = 2.

    Answer: 12

    2(3²) − 3(2) = 2(9) − 6 = 18 − 6 = 12.

  5. The product of 4x and (x − 3) is:

    Answer: 4x² − 12x

    4x × x = 4x² and 4x × (−3) = −12x, giving 4x² − 12x.

  6. Solve for n: n/3 + 5 = 11.

    Answer: 18

    n/3 = 11 − 5 = 6, so n = 18.

  7. What is the coefficient of x in the expression 7 − 4x + x²?

    Answer: −4

    The term involving x (not x²) is −4x, so its coefficient is −4.
