Solve for n
5+2(n+1)=2n
5+2(n+1)=2n -- expand brackets5+2n+1=2n -- combine like terms6+2n=2n -- subtract 2n from both sides6=0 , false.Some equations don't have a solution and this is one of them, that is perfectly fine.
\(5+2(n+1)=2n \\\\5+2n+2=2n\\\\7+2n=2n\ \ |\ subtract\ 2n\ to\ both\ sides \\\\ 7=0 \\ \\ false\)
