You divide 71 by 9 to get 7 8/9
I don't see anything, but any line that doensnt have the right angle sign is not perpendicular.
2x - 6 = 20
2x = 20 + 6
2x = 26
x = 26/2
x = 13 <==
This is pretty simple once you get used to this
First set it equal to the original and the negative one
(>_) is the bigger and equal to part
4x+5>_45 or 4x+5>_-45
Then solve for x for both
4x>_40. 4x>_-50
X>_10 X>_-25/2
