Number of shots Lia made = x
Number of shots Cliff made = y
Number of shots Kyle made = z
x=3y(Lia made 3 times as many baskets as Cliff) ------ 1)
x=z(Lia and Kyle shot the same # of baskets) ------------2)
z=12+y(Kyle shot 12 more baskets than cliff) ---------------3)
From 1) & 2), z=3y -------------------------------------------------4)
From 3) & 4), 3y=12+y --> 2y=12 --> y=6
therefore, z=12+y(6)=18
x=z=18
Lia: 18 times
Cliff: 6 times
Kyle: 18 times
