Question

Solve the system of equations and choose the correct answer from the list of options.

x + y = −3
y = 2x + 2

(5/3,4/3)
(-5/3,-4/3)
(-3/5,-3/4)
(3/4,3/5)

Answer 1

Hint:
I substitute the value of y from the second equation into the first one, so I get:
\[x + (2x + 2) = - 3\]

Answer 2

what is x?

Answer 3

idk?? D:D

Answer 4

D:

Answer 5

I can simplify that above equation as follows:
\[\begin{gathered}
x + 2x + 2 = - 3 \hfill \\
3x + 2 = - 3 \hfill \\
\end{gathered} \]

Answer 6

D: :(

Answer 7

\[3x = - 5\]

Answer 8

Now I divide both sides by 3, and I get:
\[x = - \frac{5}{3}\]

Answer 9

I think its B

Answer 10

thxx <3

Answer 11

please wait, we have to compute y

Answer 12

Dont trust my judgement listen to michele

Answer 13
