Contoh Permasalahan SPLDV dalam Kehidupan Sehari- hari
Summary
TLDRIn this video, viewers follow Doni as he embarks on a journey to buy some permen (candies) and donat (doughnuts), encountering Dea and Om Fajar along the way. Through a simple yet intriguing situation, Doni learns about the prices of these items via a system of linear equations. The video demonstrates how to solve a real-world problem involving two variables: the price of permen and donat. By applying mathematical reasoning, viewers are guided through finding the prices and checking if Doni’s Rp20,000 is enough to make his purchase. A fun and educational journey into solving SPLDV (System of Linear Equations with Two Variables).
