Answer 1

Do you know the substitution method, elimination method, or graphing method?

Answer 2

no im in 8th grade im kinda dumb can you just give me the answer

Answer 3

I can't give you the answer but i can bring you to the answer xd

Answer 4

okay can you explain

Answer 5

We have
x + y = −3
y = 2x + 2

and using the substitution method, we can substitute the second equation into the first making it

x+ (2x+2) = -3

follow so far

Answer 6

ok

Answer 7

So then solve for x
3x+2=-3
3x = -5
which means that
\[x= - \frac {5} {3}\]

Answer 8

x+y=-3

-5/3 + y = -3
y=1 1/3
