Proof is something like I have proof of u eating pie. I think it might be D.
1)
2x-y=16
-2y-x=-8
You need to solve on of the equations for x or y. I will solve the first equation for y.
2x-y=16
-y=-2x+16
y=+2x-16
Then you can substitute that y value for the y value in the second equation (2y-x=-8) can be written as 2(2x-16)-x=-8 since y=2x-16.
then you solve for x.
4x-32-x=-8
3x=24
x=8
therefore y=0 since 2(0)-8=-8
I will complete the second part of the question either in the comments or a new answer later when I have more time.
Answer:
y=2
x=5
trust me its by calculator
The answer is 2 because if the variable or numbers are close together you have to multiply those 2 numbers so that means it would look like this ---> XY=10=5 X 2=10. :)
