Desiree and Nick, the boy she was babysitting were playing basketball together. Her score was 20 points and his score was 10 points. Desiree wanted to make the game more fair, so she called a time-out and modified the rules a bit. Desiree explained that, for the rest of the game she would get 3 points per basket and Nick would get 4 points per basket. Then they played a bit longer. After the time-out, they both made the same number of baskets and ended up with a tied score. How many baskets did each person make after the time out? (its substitution math.)
