Question

Simply.


`(ab - a)/(a) =`

`(2x + y)/(y) =`
I mainly forgot how to do it. Do I divide -ab to get it alone? How do I do it?​

Answer 1

Required Answer:-

• First go to first equation

`{:}\longrightarrow`
`\sf {(ab-a)/(a)}`

• Take common

`{:}\longrightarrow`
`\sf {\frac {{\bcancel {a }}(b-1)}{{\bcancel {a}}}}`

`{:}\longrightarrow`
`{\underline{\boxed{\bf b-1)}}}`
