what is meant by of partical​

Answer 1

Answer:

The expressions forming equations have to be simplified before it can be solved with usual methods. 

Some equations may not even be linear in the beginning, but they can be brought to linear form by applying suitable operations like transposing etc.

After discussing some more applications involving age, two digit numbers, dimensions of the given figure etc. the next part of the chapter deals with Reducing Equations to Simpler Form.

The utility of linear equations is in their diverse applications such as:

a. Different problems on number

b. Ages

c. Perimeters

d. Combination of currency notes

The last exercise is based on the same containing 7 questions. For a better understanding of this chapter and to increase the fluency of forming linear equations, students must do a good practice of all solved and unsolved problems. 

For conclusion, a recap of a few important points is discussed.
