Step-by-step explanation:

I like to use a spreadsheet for repetitive calculations. The distances are computed from the distance formula:

d = √((x2 -x1)^2 +(y2 -y1)^2)

The results are shown in the second attachment. The drawing in the first attachment has the lengths rounded to the nearest tenth.

You want to solve for 'z'.
First combine like terms on either side of the equal sign.

Left side: 9z +2 ----> No like terms, leave alone

Right side: 6z - 10 -z - 4 ----> circle like terms and add
6z -z = 5z
-10 -4 = -14
Now the equation is:
9z + 2 = 5z - 14

Get all the 'z' terms on the left side and all the numbers on right side.
You can move a term to the other side if you flip the sign.

Move 5z to left side, flip the sign to -5z
Move '2' to right side, flip the sign to -2

9z - 5z = -2 -14

Add like terms
4z = -16

Divide by 4 on both sides
z = -4
