Question

If 2x-6=2/x then x-1/X will be ? A. 1 B. 2 C. 3 D. 4 With solution please

Answer 1

Answer:

C) 3

2x - 6 = 2/x --eq.1

if we take 2 common from L.H.S. of eq.1 then

2(x - 3) =2/x

after cancenlling 2 we get

x -3 = 1/x

so,

x+1/x = 3

Answer 2

Answer:

$given \: that \: \\ 2x - 6 = \frac{2}{x} \\ x - 3 = \frac{1}{x} \\ x - 1 - 2 = \frac{1}{x} \\ x - 1 = \frac{1}{x} - 2 \\ x - 1 = \frac{1 - 2x}{x} \\ multiplying \: both \: sides \: by \: \frac{1}{ x} \\ \frac{x - 1}{x} = \frac{1 - 2x}{ {x}^{2} }$

this is your answer

hope it helps to you☺️
