Hannah wrote down the set of number below (3,4,5,6) her friend wrote down the equation below 4x 2=18 which number from Hannah's set makes the equation true?

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.
