Like the numbers up for a stem and leaf chart by doing like this: heres an example lets say put these numbers in stem and leaf: 12, 14, 21, 38, 45, 46
1 | 2, 4
2 | 1
3 |8

It will quarter the result. (I think so)
So, XZ= 7x+1 and PZ= 4x-1. To figure out XP we have to subtract those two.
(7x+1)-(4x-1)
3x-2
3(8)-2
24-2
22
XP=22
Wouldn't you just do 10 divided by 12
-9(-4) / 4 - (-2)
= -9*-4 / 4 + 2
= 36 / 5
= 6 answer
12x²-9x = 0
3x(4x-3)=0
4x-3=0
4x=3
x=3/4
so either x = 0 or x = 3/4
