This guide provides a comprehensive overview of how to effectively solve mathematical problems involving two or more unknowns. It outlines a systematic four-step process: selecting a variable, writing expressions for other unknowns, forming equations, and solving those equations. Through practical examples, such as finding the dimensions of a monitor screen and determining the number of glasses of lemonade and guava juice sold, learners can apply these steps to real-life situations. Enhance your problem-solving skills in algebra and geometry.

  28. Ex 4.You sell two kinds of drinks: lemonade and guava juice. Each glass of lemonade costs $3, and each glass of guava juice costs $5. Suppose the number of glasses of lemonade you sold one day was 10 less than twice the number of glasses of guava juice you sold. Also suppose that your total sales that day were $190. How many glasses of each kind of drink did you sell that day?

  29. Ex 5.A farmer has a total of 17 pigs and chickens. The combined number of legs is 58. How many pigs and how many chickens are there?
