# Formulate the fol

Let chairs be x and tables be y.

Then the equations are

3x + 2y = 700 i.e. 3x + 2y – 700 = 0

5x + 3y = 1100 i.e. 5x + 3y – 1100 = 0

For cross multiplication method, we write the coefficients as Hence, we get = =  = =  = = x = = 100 (Cost of one chair)

y = = 200 (Cost of one table)

Now, total cost of two chairs and three tables,

2x + 3y = 2 (100) + 3 (200) = 200 + 600 = Rs. 800
