Question

Find the length of AM.

Answer 1

Answer:

AM = 26

Step-by-step explanation:

AM = MC

x+20 = 5x-4

Subtract x from each side

x+20-x = 5x-x-4

20 = 4x-4

Add 4 to each side

20+4 = 4x-4+4

24 = 4x

Divide by 4

24/4 = 4x/4

6 =x

We want AM

AM = x+20

       =6+20

      =26

Answer 2

Answer:

26

Step-by-step explanation:

x+20=5x-4

x+24=5x

24=4x

x=6

x+20

substitute 6 for x

6+20

26
