Which of the following is the solution set of 18 - 3n + 2 = n + 20 - 4n?
(a) N (b) R (c) R/{0}

Solution:

We will use the concept of linear equations in order to find the solution set.

We have the linear equation 18 - 3n + 2 = n + 20 - 4n.

The above linear equation can also be written as 20 - 3n = 20 - 3n when solved on both the left-hand and right-hand sides. Hence, for every value of n, the linear equation gets satisfied.

Hence, the solution set of the linear equation is real number R. 

Therefore, the solution set of 18 - 3n + 2 = n + 20 - 4n is R.

Thus, option b) is correct.

Which of the following is the solution set of 18 - 3n + 2 = n + 20 - 4n? (a) N (b) R (c) R/{0}

Summary:

The solution set of 18 - 3n + 2 = n + 20 - 4n is R. Thus, option b) is correct.
