Question

Which of the following is the solution set of 18 - 3n + 2 = n + 20 - 4n? Ø {0} all reals

Answer 1

I agree with the other person, the answer should be all reals.

Explanation:

Answer 2

18-3n+2=n+20-4n combine like terms on each side

20-3n=20-3n

So the above is true for all real values of n. n=(-oo, +oo) (all real values)
