An illustration of the letter 'A' in a speech bubbles


cross multiply,








use zero product property,

`x+1=0`   or  `x-3=0`

`x=-1`  or  `x=3`

Now let's check the solutions by plugging them in the original equation,

For x=-1



It's an extraneous solution, as it leads to division by zero.

For x=3,



It's true.

So, the solution of the equation is x=3
