Which of the following is the solution set of 18 - 3n + 2 = n + 20 - 4n?
A) N b) R c) R/{0}
We will use the concept of linear equations in order to find the solution set.
Answer: The solution set of 18 - 3n + 2 = n + 20 - 4n is R. Thus, option b) is correct.
Let us see how will use the concept of linear equation in order to find the solution set.
Explanation:
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.
