Answer:

False

Explanation:

Let us start with the most obvious one:

27 - z = 7

-27 - 27

_________

-z = -20

z = 20 [Plug this back into the other two equations to get the y-coordinate and x-coordinate of 4½ and -9½]; 4½ = y; -9½ = x

So, the solution is [-9½, 4½, 20].

I am joyous to assist you anytime.
