    Step-by-step explanation:

    Vanessa is trying to solve the equation for x.

    The given equation is -3 + 4x = 9, or 4x – 3 = 9

    She shouldn’t be subtracting any number in the beginning. Instead, she should do the opposite of PEMDAS:

    1) Vanessa should add 3 to both sides:

    4x – 3 (+3) = 9 (+3)

    4x = 9 + 3

    4x = 12

    2) Next, she should divide 4 from both sides:

    (4x)/4 = (12)/4

    x = 12/4

    x = 3

    Vanessa’s answer will be x = 3.
