Solve the system of equations and choose the correct answer from the list of options. 2x + y = −4 y = 3x + 2 (-6/5, -8/5 ) (-8/5, -6/5) (-5/6, -11,5) (-11/5, -6/5)

OpenStudy (anonymous):

we can substitute \[y = 3x + 2 \] in for y in the other equation

OpenStudy (anonymous):

\[2x + (3x + 2) = -4\]

OpenStudy (anonymous):

now combine the terms \[5x + 2 = -4\]

OpenStudy (anonymous):

can you solve for x now?

OpenStudy (anonymous):

would x be 7? @Austin6i6

OpenStudy (anonymous):

no

OpenStudy (anonymous):

Does that mean I divide ?

OpenStudy (anonymous):

to solve for x yes

OpenStudy (anonymous):

thats fine

OpenStudy (anonymous):

\[5x = -6\]

OpenStudy (anonymous):

now divide by 5

OpenStudy (anonymous):

-1.2

OpenStudy (anonymous):

@Austin6i6 You still there ?

OpenStudy (anonymous):

yes that is correct
