Again i am stuck on this question. Here i don’t know how to solve the equations. They’re very big equations with very large numbers. I also want to check whether i have made the correct equations or not. Please help me to solve this question. This question is from pair of linear equations in two variables chapter 3. In this question, we have to find the speed of the boat in still water and that of the stream. When a boat covers 32 km upstream and 36 km downstream in 7 hours. Also, if it covers 40 km upstream and 48km downstream in 9 hours.
