Question

how did he solve the problem y = (x+1)/(x-2) to get x= 2y+1/y-1?

Answer 1

make x subject of the formula

Answer 2

x+1=y(x-2)
x+1=yx-2y
x-yx=-2y-1
x(1-y)=-1(2y+1)
next u proceed

Answer 3

y(x-2) = x+1
yx-2y =x+1
yx-x = 1+2y
x(y-1) =1+2y
x=??

Answer 4

-x=(2y+1)/(1-y)

Answer 5

@paris818 stop using negatives when you don't have to,they'll confuse you further. look at my work above
