Answer 1

Answer:

3x + 2y = ₹80

Explanation:

this is answer

Answer 2

Explanation:

Given

we have given price of 3 note books and 2 pens is ₹ 80.

To show

we have to show in the form of a linear equation

SOLUTION:

Linear equation means an equation consists of variable and constant terms where highest power is one.

To convert the above given data into linear equations we have Variable must so, firstly convert the Equation into Variable and constant form.

let notebooks be 'x'

and pens denoted by 'y'

3 notebooks mean 3x

and 2 pens mean 2y

According to the question:

=> 3x+2y = 80

More information

The above equation e.g., 3x+2y=80 is linear equation in two Variable as there are two Variable say x and y.
