Question

Given that M is the midpoint of line segment AC, AM = x + 20, and MC = 5x - 4. Find the lenght of AM.

Answer 1

Answer:

6 units

Step-by-step explanation:

AM = MC

AM = x + 20

MC = 5x - 4

x + 20 = 5x - 4

20 = 4x - 4

24 = 4x

x = 6

Answer 2

Answer:

AM = 26

Step-by-step explanation:

x + 20 + 5x -4 = AC

x +20= 5x-4

24= 4x

6= x. AM = x+20 = 6+20= 26
