- In each of the following questions, two equations are given — I in variable x and II in variable y. Solve both equations and determine the relationship between Quantity I (values of x) and Quantity II (value of y). I. x² - 19x + 84 = 0 II. y + 9 = 15 What is the relationship between Quantity I (x) and Quantity II (y)?निम्नलिखित प्रश्न में दो समीकरण दिए गए हैं — I चर x में तथा II चर y में। दोनों समीकरणों को हल कर राशि I (x के मान) तथा राशि II (y के मान) के बीच संबंध ज्ञात कीजिए। I. x² - 19x + 84 = 0 II. y + 9 = 15 राशि I (x) तथा राशि II (y) के बीच क्या संबंध है?
