The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.
