Answer:
The solution set is the set of all real numbers.
Step-by-step explanation:
Solve: \(18-3n+2=n+20-4n\)
Like terms are those terms which have same variable to the same power:
Combine like terms;
\(20-3n=20-3n\)
Subtract 20 from both sides we get;
\(20-3n-20=20-3n-20\)
Simplify:
\(-3n=-3n\)
Add 3n to both sides we get;
\(-3n+3n=-3n+3n\)
Simplify:
\(0=0\) for all n
Thus, the given system is dependent.
Therefore, the solution set is set of all real numbers.
