Question

Siri bought 3 notebooks and 2 pens for Rs.80 express this information in a linear equation ?​

Answer 1

Answer:

The linear equation is:

3x + 2y = 80

Step-by-step explanation:

Let x as notebooks and y as pens

The linear equation is:

3x + 2y = 80

Answer 2

Answer:

3x+2y =80

Step-by-step explanation:

let the price of  the notebook = x

no of notebooks bought by Siri =3

total cost of notebooks = 3x

let the price of the pen = y

no of pens bought by Siri= 2

total cost of pens = 2y

total amount = total cost of notebooks +total cost of pens

                     =3x +2y

given that total amount =Rs. 80

therefore,  3x+2y=80

linear equation using this information

                3x+2y =80
