Question

If (x-1)/x =20, then x=

Answer 1

Step-by-step explanation:

The equation is given below as

`(x-1)/(x)=20`

Step 1:

Cross multiply

`\begin{gathered} (x-1)/(x)=\frac{20}{} \\ x-1=20* x \\ x-1=20x \end{gathered}`

Step 2:

Collect similar terms, we will have

`\begin{gathered} x-1=20x \\ 20x-x=-1 \\ 19x=-1 \\ divide\text{ both sides by 19} \\ (19x)/(19)=-(1)/(19) \\ x=-(1)/(19) \end{gathered}`

Hence,

The final answer is

`\Rightarrow x=-(1)/(19)`
