Best ResponseYou've already chosen the best response.0ok, so we have our two equations 3x+y=30 and x+y=22

anonymous

Best ResponseYou've already chosen the best response.0isolate x or y in one of the equations and then plug it into the other equation

anonymous

Best ResponseYou've already chosen the best response.0so isolate x in the second equation x+y=22

anonymous

Best ResponseYou've already chosen the best response.0nope, we're just looking at x+y=22 right now

Best ResponseYou've already chosen the best response.0so what will it be?

anonymous

Best ResponseYou've already chosen the best response.0so we know there are 18 chocolate wafers. how many strawberry are there?

anonymous

Best ResponseYou've already chosen the best response.0substitute it back into this equation x+y=22

ccchristian1

Best ResponseYou've already chosen the best response.0to what number ??

anonymous

Best ResponseYou've already chosen the best response.0well we just found that y was 18

anonymous

Best ResponseYou've already chosen the best response.0x+y=22 If y is 18, what is x

anonymous

Best ResponseYou've already chosen the best response.0correct so there are 4 strawberry and 18 chocolate

anonymous

Best ResponseYou've already chosen the best response.04 x 3 + 18 x 1 = 30 18 + 4 = 22
