  1. If 9 − x = 4, what is the value of 3x?

    Answer: 15

    x = 5; therefore 3x = 15.

  2. Solve for x: x/3 + x/6 = 5

    Answer: x = 10

    Common denominator: 2x/6 + x/6 = 3x/6 = x/2 = 5 → x = 10.

  3. In the equation 4x + b = 22, if x = 3, what is the value of b?

    Answer: b = 10

    4(3) + b = 22 → 12 + b = 22 → b = 10.

  4. Solve for x: 3x − 5 = 2(x + 4)

    Answer: x = 13

    Distribute: 3x − 5 = 2x + 8; subtract 2x: x = 13.

  5. A scale displays 135 pounds, but it consistently adds 5 pounds to every reading. What is the person's actual weight?

    Answer: 130 pounds

    Actual + 5 = 135 → actual = 130 pounds.

  6. If 0.5x + 1.5 = 4, what is the value of x?

    Answer: x = 5

    Subtract 1.5: 0.5x = 2.5; divide by 0.5: x = 5.

  7. A movie theater sells adult tickets for $12 and child tickets for $8. A family bought 1 child ticket and spent $68 total. How many adult tickets did they buy?

    Answer: 5

    12a + 8 = 68 → 12a = 60 → a = 5.
