Hi there. Here's how I would approach the problem: "india has 2649 more universities than united states" "their combined total is 14,165." But if I = 2649 + S, then wherever you see the variable "I", you can So I + S = 14,165 can turn into 2649 + S + S = 14,165. And now you just need to solve for S. Cheers, | ||||||||||||
