Substitution.
OpenStudy (kayla2001):
I need this fast please
OpenStudy (anonymous):
Since it says y = x-2, then we can put that in the first equation.
OpenStudy (anonymous):
So it is x - 2 = 6 - x
OpenStudy (anonymous):
First, add x + x

I thought it was b or c
OpenStudy (anonymous):
That gives you 2x.
OpenStudy (anonymous):
Then add 2 + 6. @kayla2001
OpenStudy (kayla2001):
well am I right
OpenStudy (anonymous):
Just follow what I am doing. What is 2 + 6?

OpenStudy (anonymous):
Yes, now what's 8 \(\div\) 2?
OpenStudy (kayla2001):

Yes, so the value of x is 4.
OpenStudy (anonymous):
Because it is the easiest one to choose.
OpenStudy (anonymous):
*use not choose
OpenStudy (kayla2001):
its aaaaaaaaaaaaaaaaaaa
OpenStudy (anonymous):
@kayla2001 We can use the value of x in one of the equations to find the value of y.

y=6-4
Can you figure this out?
OpenStudy (anonymous):
To find the value of y, you subtract 4 - 2, so what is the value of y? @kayla2001
OpenStudy (holly00d1248):
right coordinates wrong order Kayla try again
OpenStudy (kayla2001):
o c
OpenStudy (anonymous):
@kayla2001 Can you figure out 4 - 2 for the value of y? We already have 4 for the value of x.

Whats o c
OpenStudy (kayla2001):
2
OpenStudy (holly00d1248):
so if X=4 and Y=2 whats the answer.
OpenStudy (holly00d1248):
@kayla2001 are you there
OpenStudy (anonymous):
Yes, what choice is your answer? @kayla2001
