Question

If x + 1 by x = 4 then find the value of x - 1 by x

Answer 1

Answer:

Step-by-step explanation:

4-1=3

Answer 2

Answer:

The value of x - 1 by x = -2

Step-by-step explanation:

 Given that:      $\frac{x+1}{x} =4$

                       ⇒ $x+1=4x$

                       ⇒3x=1

                       ⇒$x=\frac{1}{3}$

now we have to find   $\frac{x-1}{x}$

putting x=1/3 in above equation we get

⇒$\frac{x-1}{x} =\frac{\frac{1}{3} -1}{\frac{1}{3} }$

⇒$\frac{x-1}{x} =\frac{\frac{-2}{3}}{\frac{1}{3} }$

⇒$\frac{x-1}{x} =-2$
