    Answer:

    4

    Step-by-step explanation:

    The equation written by her friend is 4x+2=18.

    To find the number from Hannah’s set (3,4,5,6) that will make the equation true, we will need to find the value of x in the equation and check if the resulting value of x is a member of the set. From the equation;

    4x = 18-2

    4x = 16

    Dividing both sides by 4 we have;

    4x/4 = 16/4

    x = 4

    Therefore the number from Hannah’s set that makes the equation true is 4.
