    x = 2/3 x = - 1/3

    Step-by-step explanation:

    | 3x - 1/2 | = 3/2

    We have two solutions, one positive and one negative

    3x-1/2 = 3/2 and 3x-1/2 = - 3/2

    Add 1/2 to each side

    3x-1/2+1/2 = 3/2+1/2 and 3x-1/2+1/2 = - 3/2+1/2

    3x = 4/2 3x = - 2/2

    3x = 2 3x = - 1

    Divide by 3

    3x/3 = 2/3 3x/2 = - 1/3

    x = 2/3 x = - 1/3
