the price of 3 notebooks and 2 textbooks is rupees 135 but a notebook cost rupees 5 more than the textbook find the cost of both the notebook are textbook​

Answer 1

Answer:

Step-by-step explanation: Let the cost of 1 notebook be Rs.x and 1 textbook be Rs.y.

Then ATQ,

=> 3x + 2y = 135------(1)

Also

=> x - 5 = y

=> (x - y = 5)2-------(2)

ADD (1) and (2).

=> 3x + 2y + 2x - 2y = 135 + 10

=> 5x = 145

Thus x = 29

Thus y = 24

Thus the cost of 1 notebook is Rs.29 and 1 textbook is Rs.24
