The question is incomplete. The complete question is here
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?
Answer:
The number from Hannah's set which makes the equation true is 4 ⇒ 2nd answer
Step-by-step explanation:
Let us solve the equation to find which number will make the equation true
∵ 4 x + 2 = 18
- Subtract 2 from both sides
∴ 4 x = 16
- Divide both sides by 4
∴ x = 4
The number from Hannah's set which makes the equation true is 4
There another solution, that substitute x in the equation by each number in Hannah's set, the number which makes the left hand side is equal to the right hand side, then this number is your choice
