Question

a library takes charge of rs 5 for issuing a book for one day and rs 1 per day there after if ritu had taken book for x days and y be the total amount to be paid ,the linear equation in two variable for this situation

Answer 1

the equation will be=

y=x+5

its very simple

Answer 2

Given:

Charges that the library takes for issuing a book = Rs. 5

Charges that the library takes after issuing a book = Rs. 1 per day

No. of days for which Ritu had taken the book = x

Total amount to be payable by Ritu = Rs. y

To find:

The linear equation in two variable (x and y) for this situation.

Solution:

We can say that:

y = Charge for 1st day + Charge for rest of the days

y = 5 + (x-1)1

y = 5 + x - 1

y = x+4

Thus, if Ritu had taken book for x days and y be the total amount to be paid ,the linear equation in the given two variables for this situation will be y = x+4.
