<h3>I'll teach you how to solve |x-7|=x-7</h3>
-----------------------------------------------
|x-7|=x-7
For each absolute find positive and negative intervals:
For x<7:
No solution
Merge overlapping intervals:
x 
7
Your Answer Is x 7
plz mark me as brainliest :)
Hope this helps the seconds one I ease my for sure but the first one I’m pretty sure is right!
Step-by-step explanation:
To find the perimeter of something, we add all of the measurements of the sides together.
A rectangle has 4 sides, this means we must double the algebraic hints given to us.
If we add them all up together it will look like this:
x-9+x-9+3x-4+3x-4=138
If we simplify it by collecting the like terms:
8x-26=138
We add 26 onto 138
8x=164
To find out what x equals, we divide by 8:
164÷8= 20.5
Answer:
x=20.5cm
x-9 is 11.5
3x-4 is 57.5
I know that you will not give 100 points but just wanted to help.
