What is the solution set of 18 - 3n + 2 = n + 20 - 4n?

Solution:

18 - 3n + 2 = n + 20 - 4n [Given]

Grouping the like terms on either side, we can write it as

20 - 3n = 20 - 3n

By solving both on LHS and RHS

0 = 0

For every value of n, the linear equation is satisfied.

Therefore, the solution set is real number R.

What is the solution set of 18 - 3n + 2 = n + 20 - 4n?

Summary:

The solution set of 18 - 3n + 2 = n + 20 - 4n is the real number R.
