Question

...

Answer 1

you have two equations:
\[x + y = 165\]
\[2x + 3.50y = 465\]
x - number of junior
y - number of senior
Solve for both!

Answer 2

I mean just solve for x

Answer 3

how do I do that?

Answer 4

@pinkmommy to solve for a variable isolate one by itself in the first equation. Such as: y=165-x. Now fill that into the other equation. 2x + 3.50(165-x) = 465. So now you have 2x + 577.5 - 3.5x = 465. Combine the X terms, subtract 577.5 from each side. X = 75. So take X and fill it in. 75 + y = 465. 465 - 75 = Y, Y = 390.

Answer 5

I'm sorry. I solved this already.
