on the second equation you can add the 2 to both sides and get x by itself and ready to put into the next equation
OpenStudy (ashes.boom):
so you would have 3 + 2y = 11 and x = -4y + 2
OpenStudy (ashes.boom):
then you can put it in like this:
3(-4y + 2)+2y=11
OpenStudy (ashes.boom):
can you solve it?
OpenStudy (narissa):
its hard

3 times -4 yes
OpenStudy (narissa):
-12y+6+6y=11?
OpenStudy (ashes.boom):
almost
you dont need to mulitply the 2y by 3 because its outside of the parentheses but evey thing else is right :)
OpenStudy (ashes.boom):
-12y + 6 + 2y = 11
then you can combine the like terms: aka add 2 to the -12
OpenStudy (narissa):
is both the answers -1/2

-14y+6=11
OpenStudy (ashes.boom):
-10y + 6 = 11
because you are adding the 2 to the negative 12
Not subtracting 2 from the negative 12
OpenStudy (narissa):
oops
OpenStudy (ashes.boom):
no problem :)
OpenStudy (ashes.boom):
then you can subtract 6 from both sides which gets you what?
