Find x and AB
Given: AM = 2x+1, MB = 3x+2, and AB = 6x - 4
Find: x and AB
I got the answer for a type of question like this that consists of two terms. Unfortunately, I got lost trying to solve a question with 3 terms.
I tried making them equal to each other 2x + 1 = 3x + 2. Then I would set the answer equal to 6x - 4 but that didn't work.
The answers are x = 7 and AB = 38.
Re: Find x and AB
Okay, so I figured it out.
I was supposed to do the following: 2x+1 + 3x+2 = 6x - 4
5x - 6x = -3 - 4
-x = -7
x = 7
then just substitute 7 into the x's.
I'm sad that I couldn't get this first try. Sigh.
