Question

If x+1/x=3, find the value of x-1/x?​

Answer 1

Answer:

x+1=3x

3x-x=1

2x=1

x=1/2

Answer 2

Answer:

-1

Step-by-step explanation:

First find the value of x

x+1/x = 3

=> x+1 = 3 × x

=> x+1 = 3x

=> x - 3x = -1

=> -2x = -1

=> 2x = 1

=> x = 1/2

Therefore, x= 1/2

Now , put the value of x in x-1/x

1/2-1/x

= 1/2-1 ÷ 1/2

= 1-2/2 × 2/1

= -1/2 × 2

= -1/1

= -1
