Example 15.Three chairs and two tables cost Rs 1850. Five chairs and three tables cost Rs 2850. Find the cost of two chairs and two tables.
Solutions:- Let price of one chair be Rs. x and price of one table be Rs. y.
Price of 3 chairs and 2 tables is 3x + 2y
and price of 5 chairs and 3 tables is 5x + 3y
and 3x + 2y = 1850 ------------------- (2)
Multiplying equation (1) be 2 and equation (2) by 3 and then subtracting (2) from (1) we get
Putting x = 150 in equation (2) we get
