I have my notes here that will help you in answering the problem:

Test to determine if a function y=f(x) is even, odd or neither: Replace x with -x and compare the result to f(x). If f(-x) = f(x), the function is even. If f(-x) = - f(x), the function<span>is odd.

I hope my answer has come to your help. God bless and have a nice day ahead!

What does x and y equal

GaryK [48]

Answer:

x=5, y=-3

Step-by-step explanation:

we can find the answer by plugging in x=3y+14 to the second equation

5(3y+14)-2y=31

simplify

15y+70-2y=31

13y=-39

y=-3

now, plug in this to the initial equation x=3y+14

x=3(-3)+14

x=-9+14

x=5
