Answer 1

Answer:

8

Step-by-step explanation:

$x - - \frac{1}{x} = 2 \\ x - ( - \frac{1}{x} ) = 2 \\ x + \frac{1}{x} = 2 \\ ({x})^{3} + ( { \frac{1}{x}) }^{3} = ({2})^{3} \\ {x}^{3} + \frac{1}{ {x}^{3} } = 8$

Answer 2

Answer:

7 7/8

Step-by-step explanation:

-1x==2-x

x=2-x/-1

x=2-(-x)

x=2

so, 2³-1/2³

8-1/8

64-1=63/8

so, mixed fraction is 7 7/8
