Does anybody know of some good mathematics formula books?

i am currently stuck with: X/5

Can i turn this into something else, like: X-5?

i got this from the equation: X+ 5y = 3000

then: 5y = 3000 - x

y = 600 - x/5

Now i have to put this into a Lagranges equation:

f(x,y) = 100x^1/2 + 100y^1/2-1000

wich i now get: 100x^1/2 + 100 (600-x/5)^1/2-1000

how do i solve this?
