First simplify by completing the addition. 4z-7+4z-7+8x+2=180 so
8z+8x-12=180 then 8z+8x=192. That's as far as you can get. If z=1 then x=23
if z=0 then x=24. But with what you gave you will never know for sure what each is.

Collecting terms, we have
8z + 8x - 12 = 180
Add 12 to both sides of the equation
8z + 8x = 192
Divide both sides of the equation by 8
z + x = 24. This is the relation between z and x. You can solve for z in terms of x, or x in terms of z. This is the equation for a line through the points (0, 24) and (24, 0), which is to say that both the x and y intercepts are 24.
x = 24 - z (subtract z from both sides)
z = 24 - x (subtract x from both sides)
8z + 8x - 12 = 180
Add 12 to both sides of the equation
8z + 8x = 192

4z - 7 + 4z - 7 + 8x + 2 = 180
+ 7 + 7 - 2 = 180 + 7 + 7 - 2
4z + 0 + 4z + 0 + 8x + 0 = 192
8z + 8x = 192
( 8z + 8x ) = 192 =
8 8
( z + x ) = 24
+ 7 + 7 - 2 = 180 + 7 + 7 - 2
4z + 0 + 4z + 0 + 8x + 0 = 192
8z + 8x = 192
( 8z + 8x ) = 192 =
8 8
( z + x ) = 24

I think this is right but I'm not positive!
4z-7+4z-7+8x+2=180 x=0 z=24
8z-14+8x+2=180
8z-12+8x=180

8z=192+8x
