Question

If the cost of 5 tables exceeds the cost of eight chairs by Rs. 150. Write the linear equation in two variables to represent the statement. Also, find the cost of 1 table if the cost of one chair is RS. 240 9. Give the geometric representation of 2x + 1 = x – 4 as an equation in (a)one variable
(b) in two variable

Answer 1

Answer:

Let cost of 1 table be x rupees

And cost of 1 chair be y rupees

therefore , cost of 5 tables =5x

cost of 8 chairs= 8y

and 5x-8y=156

this is the linear equation in two variables x and y that represents the statement.

Also given that one chair is 240 rs. Therfore cost of 1 table would be x= (156+8(240)
