Question

cost of 3 chairs and 4 tabless is rather 1200 how will you communicate the above information in the form of a linear equation

Answer 1

Lets assume that cost of 1 chair is x and cost of 1 table is y.
Its given that cost of 3 chairs and 4 tables is 1200.

Cost of 3 chairs = 3 x
Cost of 4 tables 4 y

The linear equation that represents the above information is :

3 x + 4 y = 1200

Answer 2

let cost of chair=x
cost of tables=y
linear equation= 3x+4y=1200
