continuing from my prev post
Say u want to find a number that gives the same result when divided by x and when x is subtracted from that... Let, the number be y then y/x=y-x => y=xy-x^2 => y(1-x)=-x^2 => y=(x^2)/(x-1) -----------(1) where x != 1 Got it???? Means if u want to find a number for which [that number]/6=[that number] -6 the just replace the values in equation (1) i.e. y=36/5=7.2
if y=(x^2)/(x-1) then
u can write it as follows
=> y=(x+1) + 1/(x-1)
this is the soln u have got... right??? enjoy math.......
