Finding the X in a supply and demand equation

Much has been said about prohect x

ProjectXIsCriminalBecause it’s promoting

immorality among our children…

ProjectXIsCriminalBecause it deviates from

our societal norms, ethical principles and values.

ProjectXIsCriminalBecause old tweeps are

jealous.They didn’t enjoy this things.We are in effing
21ST CENTURY.So y’all old tweeps STFU.
i personally believe project X should no be stopped
where will the single mums that most male villagers fuck with around come from?
where will the sex workers come from?
project X serves as supply matrix for future demand.

We need no single mother nor sex worker

find z
assume

single mum=x
the guy=y
sex worker=z

solve the following set of multidimensional equations to find how z is achieved(1/2marks)

x(y^5)-z

x(y^3)-z

9(y-(x+z))

y-(x+y)^99
