When you lift a ball with a force of 82N, the ball accelerates upward with an acceleration of a. If you lift with a force of 92N, the balls acceleration is 2a. Find the weight of the ball, and the acceleration a.

I tried solving this via substitution algebra, but the answer still didn't work, PLEASE help!!!!
