Answer:
Step-by-step explanation:
What i would do is multiply both sides by 2z + 1
so you get z-6=20z+10
-19z=16
z=-16/19
x^2-9x-6=0
Use the quadratic formula to get (9+sqrt(105))/2 or (9-sqrt(105))/2
24 slices because you would do three apples times eight slices so you would get 24 slices
Y=72 for the first option,as for the second one i don't know. Hope i helped on the first equation though :)
