Q:
# Point M is the midpoint of AB . AM= 3x+3, and AB=8xβ6What is the length of AM?The answer is 21 but i don't know the steps to get it. HELP

Accepted Solution

A:

AM= Half of AB

or, 3x+3=(8x-6)/2

or, 6x+6=8x-6

or, 2x=12

Therefore,x=6

so,AM=3*6+3=21

or, 3x+3=(8x-6)/2

or, 6x+6=8x-6

or, 2x=12

Therefore,x=6

so,AM=3*6+3=21
