Question

If x-1/x=6. find x+1/x

Answer 1

x-1/x = 6
or x -1 =6x
or -1 = 6x -x
or -1 = 5x
or -1/5 =x
or -0.2 = x


x + 1/x
= -0.2 +1/-0.2 LCM of 0.2 and 1 = 1
=-0.2/1×1 + 1/-0.2 ×5
= -0.2/1 + 1/-1
= 1.2

Answer 2

x-1/x = 6

or x -1 =6x

or -1 = 6x -x

or -1 = 5x

or -1/5 =x

or -0.2 = x

x + 1/x  

= -0.2 +1/-0.2 LCM of 0.2 and 1 = 1

=-0.2/1×1 + 1/-0.2 ×5

= -0.2/1 + 1/-1

= 1.2
