Question

3) What limitations are there to using linear equations in the real world?

4) Do you use linear equations at home or at your job? If yes, please give one or two examples.

Answer 1

3. The disadvantage of using linear equation in real world is, it deals with quantity only not with quality. It deals with those things which can be measured but not for those which cannot be measured.

If we want to find the numerical quantity, we can use linear equations

But sometimes it is not gud where the conditions is of atleast or atmost.

2. We do use linear equations in our daily lyf. Although we are so habitual that we donot need to use pen and paper to solve , we can solve them in our minds directly.

For example: we bought 2bats and 3 balls for Rs 230. Next time we bought 3 bats and 2 balls for Rs 320. What is the cost of each bat and ball?

We can use linear equations to find these values.

In this way, there are many ways where we can use linear equations.
