The cost of a table is 100 more than half the cost of a chair. Write this statement as a linear equation in two variables.
Let the cost price of a table be ₹ x and that of a chair be ₹ y. Since the cost price of a table is 100 more than half the cost price of a chair. ∴x = 1/2y + 100 ⇒ 2x = y + 200 or 2x – y – 200 = 0.
