help
OpenStudy (mertsj):
Replace y in the first equation with 3x+2 from the second equation.
OpenStudy (anonymous):
you can substitute values
OpenStudy (anonymous):
is that right mertsj
OpenStudy (mertsj):
Then get it equal to 0 and try to factor it.

(−7, −2)
(7, 2)
(5, 10)
OpenStudy (anonymous):
last one
OpenStudy (mertsj):
Did you plug it into both equations to see if that choice makes both equations true?
OpenStudy (mertsj):
