  1. Solve: 5x = 45

    Answer: x = 9

    Divide both sides by 5 to get x = 45 ÷ 5 = 9.

  2. What is the next number in the sequence: 3, 6, 12, 24, ___?

    Answer: 48

    Each term is multiplied by 2, so 24 × 2 = 48.

  3. If x/4 = 7, what is x?

    Answer: 28

    Multiply both sides by 4 to get x = 7 × 4 = 28.

  4. A sergeant has y officers on duty. After 3 more officers join the shift, there are 15 on duty. What was y?

    Answer: 12

    The equation is y + 3 = 15, so y = 15 − 3 = 12.

  5. What is the missing number in the sequence: 100, 91, 82, 73, ___?

    Answer: 64

    Each term decreases by 9, so 73 − 9 = 64.

  6. Solve for x: 6x − 4 = 2x + 16

    Answer: x = 5

    Subtract 2x from both sides: 4x − 4 = 16; add 4: 4x = 20; divide by 4: x = 5.

  7. If n + n + n = 39, what is n?

    Answer: 13

    The equation simplifies to 3n = 39, so n = 39 ÷ 3 = 13.
