OpenStudy (narissa):

OpenStudy (anonymous):

the substitution way is the way we did before i gotta catch the bus but when im on the bus i will try to get back no in about like 15 min

OpenStudy (ashes.boom):

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

OpenStudy (narissa):

do i minus 2

OpenStudy (ashes.boom):

its okay just go step by step if you need help just tell me

OpenStudy (ashes.boom):

you want to distribute the 3 into each thing in the parentheses

OpenStudy (narissa):

do i do 3 times 4

OpenStudy (ashes.boom):

-4

OpenStudy (ashes.boom):

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

OpenStudy (narissa):

-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?

OpenStudy (narissa):

-10y=5

OpenStudy (narissa):

its not letting me click best response or close it whats going on

OpenStudy (ashes.boom):

yep and then divide by -10 on both sides

OpenStudy (narissa):

@iGreen

OpenStudy (narissa):
