#1**+1 **

'z' is just an unknown to solve for ...it could be 'x'

-8x + 12 = -12 subtract 12 from both sides

-8x = -24 divide both sides by -8

x = 3 (or z = 3)

#2**+2 **

-8z + 12= - 12

-8z= -12-12

-8z= -24

Because both are negative, we can just take them as positive

8z=24

z= 24/8

z=3

Hope that helps :)
