Try this option: 1. according to the condition Kris scored '2x' points, Julio did 'x' points (Kris scored 2 times as many points as Julio). 2. according to the condition Kris'_points+Julio's_points=36_points. It means, that x+2x=36. 3. If to solve this equation (2x+x=36), then Julio scored x=12 points, Kris scored 2x=12*2=24 points.
