Question

Write a linear equation in two variables to represent the the statement "Four times the cost of a table is equal to seven times the cost of a chair ' '.From the graph of a above linear equation,find the cost of one chair if the cost of one table is Rs.1050.​

Answer 1

Step-by-step explanation:

let the cost of one table = x and cost of one chair = y then the equation will be:- 4x = 7y

Answer 2

Answer:

Eq: 4x=7y

Cost of one chair = Rs 600

Step-by-step explanation:

Let the cost of one table = x and cost of one chair = y

Equation : 4x = 7y

x=1050 ,

then y = 4x/7

y= 4*1050 / 7

y = Rs 600
