Question: Together 3 friends watched 411 short videos. Kelsey watched 43 more than Ekon. Ekon watched 17 less than Uma. How many videos did Kelsey watch?
Answer with step-by-step thinking: Let U = the number of videos Uma watched. Ekon = U - 17. Kelsey = (U - 17) + 43 = U + 26. U + U - 17 + U + 26 = 411. 3U + 9 = 411. 3U = 402. U = 134. Kelsey = 134 + 26 = 160 videos. Kelsey watched 160 videos.
So the answer is 160.
