Answer:


MN = 9.2

Explanation:

Given


MN = 6x - 4


NO = 4x + 2


MO = 20

Required

Find MN

Since N is between M and O, then:


MO = MN + NO

This gives:


20 = 6x - 4 + 4x + 2


20 = 6x + 4x- 4 + 2


20 = 10x -2


10x = 20 +2


10x = 22


x = 2.2

To solve for MN, substitute 1.4 for x in
MN = 6x + 4


MN = 6 * 2.2 - 4


MN = 9.2
