Question

the cost of four chair and five tables is 3200 ₹ . write a linear equation in variable for this statement and find out its two solution ​

Answer 1

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

The linear equation is

4x+5y=3200

take x=5

4(5)+5y=3200

5y=3200-20

5y=3180

y=636

therefore the first solution is

(5 , 636)

if we take y=4

4x+5(4)=3200

4x=3200-20

4x=3180

x=795

therefore the second solution is (795 , 4)

Answer 2

Answer: hey mate here you go

let cost of one table be x

and cost of one chair be y

=4x+5y=₹3200
