Algebraic Expressions, Solving For X - Quiz

Quiz Preview

  • 2. 

    -2 + x = -27

    • X = 17

    • X = -25

    • X = 4

    • X = 15

    Correct Answer
    A. X = -25
    Explanation
    To solve the equation -2 + x = -27, we need to isolate the variable x. To do this, we can add 2 to both sides of the equation. This will give us x = -25. Therefore, the correct answer is x = -25.

    Rate this question:

  • 3. 

    1/2x = 9

    • X = 18

    • X = 11

    • X = -9

    • X = 27

    Correct Answer
    A. X = 18
    Explanation
    To solve the equation 1/2x = 9, we can multiply both sides of the equation by 2 to eliminate the fraction. This gives us x = 18. Therefore, the correct answer is x = 18.

    Rate this question:

  • 4. 

    3 (2 + x) = 0x = 2

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given equation is 3(2 + x) = 0x = 2. However, this equation is not mathematically valid as it contains two equal signs, which is not allowed. Therefore, the correct answer is False.

    Rate this question:

  • 5. 

    -x - 11 = 4x = -15

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given equation is -x - 11 = 4x = -15, which is not a valid equation as it contains two equal signs. Therefore, the correct answer cannot be determined based on the given information.

    Rate this question:

  • 6. 

    -3/4x = 15 x = 20

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given equation is -3/4x = 15. To solve for x, we need to isolate x on one side of the equation. To do this, we can multiply both sides of the equation by -4/3. This will cancel out the -3/4 coefficient on x, leaving us with x = -4/3 * 15. Simplifying this, we get x = -20. Therefore, the statement x = 20 is false.
