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