2x+4y=2800 Start from here
OpenStudy (anonymous):
alright
OpenStudy (anonymous):
Then get Y by itself
OpenStudy (anonymous):
-4
OpenStudy (anonymous):
Uhhh, not quite. I mean isolate Y on one side of the equation.
So subtract 2x from both sides, then divide by 4

i got 699
OpenStudy (anonymous):
Y = (2800 - 2x) / 4
OpenStudy (anonymous):
ok then you...
OpenStudy (anonymous):
y=-1/2x+700
OpenStudy (anonymous):
where did u get 700

2800/4
OpenStudy (anonymous):
ok now do i divide 700 by 2
OpenStudy (anonymous):
Let there be s students and a adults. Since each s-ticket costs 2 (ignoring units) and each a-ticket costs 4, the total cost of the s-tickets is 2s and the total cost of the a-tickets is 4a. Since the sum of these is 2800, we have: \[ 2s + 4a = 2800 \rightarrow s + 2a = 1400. \]So, s must be even.
Hope that helped! :)
