Question

The price of 3 notebook and 2 textbook is rupees 135 button notebook cost rupees 5 more than the textbook find the cost of both the notebook and textbook

Answer 1

Step-by-step explanation:

Let, Notebook price = X

Textbook price = Y

3X + 2Y = 135

Also, X = Y + 5

Now put the value of X in the equation above

3(Y + 5) + 2Y = 135

3Y + 15 +2Y = 135

5Y = 120

Y = 24

Notebook price = 29

Textbook price = 24
