  • Q #1: Which of the following is the value of x in the equation below  

    A. x= -4/3 or x=2

    B. x= -1 or x=2

    C. x =-2 or x= 1

    D. x= -3/2 or x= 1/2

    Answer Explanation

    we find the value of x by applying the absolute conditions to the given equation.

    First, add 2 to both sides of equation

    Add 10 to both sides of the equation

    Next, we apply the absolute rule:

    If u=a, a>0, then u=a or u=-a

    In this case a=5, which is greater 0.

    The first condition becomes

    Solving for x

    The second condition becomes

    Solving for x

    Then, the value of x is -4/3 or 2.
