Answer:
9 and -4 is the answer it should be correct
Answer:
X = S-R
Step-by-step explanation:
I don't really know what it means, maybe what makes sense is X = S-R?
The answer is D. It can't be A, because that would be if 4 people forwarded it to 5 people each. It can't be B, because that would be Kris, the people she forwarded it to, and the people they forwarded it to, it can't be C, because that the people Kris forwarded it to, the people they forwarded it to, and the people they forwarded it to, it's missing the 4th round of people. So it must 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.
