plz help asap
what is the answer
and what does z stand for??!?
'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)
-8z + 12= - 12
Because both are negative, we can just take them as positive
Hope that helps :)
