Romila went to a stationery shop and purchased 2 pencils and 3 erasers for Rs 9. Her friend Sonali saw the new variety of pencils and erasers with Romila, and she also bought 4 pencils and 6 erasers of the same kind for Rs 18. Represent this situation algebraically and graphically

Solution:

Let the cost of pencils be Rs x and the cost of erasers be Rs y

Algebraic representation:

⇒ 2x + 3y = 9 be equation (1)

⇒ 4x + 6y = 18 be equation (2)

To represent graphically.

⇒ From equation (1)

When x = 0; y = 3 and x = 4.5, y = 0

⇒ From equation (2)

When x = 0; y = 3 and x = 3; y = 1

Graphical representation
