Ash · Answer 1

Do 5x + 1 instead of 5x + 20, because there was more than likely a mistype.

Now we are also looking for the reciprocal so we do (5x + 1) / 20

Either that is the answer or there is something missing. If this is not the answer then there needs to be a number we can set the equation equal to

The answer would more than likely to be 4 ...

because u divide 5 on both sides and it will give you x=4
