Question

a person bought 3 pens and 2 pencils together and paid rs 80/- Express this 8n the form of a linear equation​

Answer 1

Answer:

3+2-8n I think this is ans

Answer 2

Given,

Price of 3 pens and 2 pencils = Rs.80

To find,

The linear equation to express this situation.

Solution,

We can easily solve this mathematical problem by using the following mathematical process.

General form of linear equation :

ax + by + c = 0

Let, price of one pen = Rs. x

And price of one pencil = Rs. y

Total price = (3×x + 2×y) = Rs. (3x+2y)

According to the data mentioned in the question,

3x+2y = 80

3x+2y-80 = 0 [Linear equation]

Here, a = 3, b = 2, c = -80

Hence, the linear equation will be 3x+2y-80 = 0
