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

homecomingchicken · Answer

okay can you explain

snowflake0531 · Answer

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

homecomingchicken · Answer

ok

snowflake0531 · Answer

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

snowflake0531 · Answer

x+y=-3

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