Question

Write a linear equation in two variables to represent the statement :

“Four times the cost of a table is equal to seven times the cost of a chair.”

Draw the graph for the above given situation and find the cost of one chair if

the cost of one table is Rs. 1050 from graph only.​

Answer 1

Answer:

4x = 7y is the linear eq. in 2 variables and the cost of one chair is ₹ 600.

Step-by-step explanation:

let the cost of the table be x and the cost of the chair be y.

According to the question..

4x = 7y

Given that the cost of the table is ₹ 1050

Then putting the value of x in the given eq.

4× 1050 = 7y

y = ( 4 × 1050 ) ÷7

y = 4200/7

y = ₹ 600
