2/5+1/10=1/2(n+4)
We move all terms to the left:
2/5+1/10-(1/2(n+4))=0
Domain of the equation: 2(n+4))!=0We calculate fractions
n∈R
()/(2(n+4))*5*10)+(40nn/(2(n+4))*5*10)+(10nn/(2(n+4))*5*10)=0
We calculate terms in parentheses: +()/(2(n+4))*5*10)+(40nn/(2(n+4))*5*10)+(10nn/(2(n+4))*5*10), so:
)/(2(n+4))*5*10)+(40nn/(2(n+4))*5*10)+(10nn/(2(n+4))*5*10
We can not solve this equation
