1. `y=4x-3`, find Inverse of a function

Solution:
`y=4x-3`

Replace all x with y and y with x.
`x=4y-3`

Now, Solve `x=4y-3` for y

Interchange sides
`=>4y-3=x`

`=>4y=x+3`

`=>y=(x+3)/4`

2.`y=2/(x-5)`, find Inverse of a function

Solution:
`y=2/(x-5)`

Replace all x with y and y with x.
`x=2/(y-5)`

Now, Solve `x=2/(y-5)` for y

Interchange sides
`=>2/(y-5)=x`

`=>(y-5)/2=1/(x)`

`=>(y-5)=1/x xx 2`

`=>y-5=2/x`

`=>y=2/x+5`
