Answer:
n + 5 or 5 + n
Explanation:
add 5 to n, tanya's current age, to find how old she'll be in 5 years.
since the variable n is not defined, the answer cannot be simplified further than n + 5.
if n had been defined, you would be able to figure out her exact age after 5 years, which would be the fully simplified answer. for example, if n were to equal 10, then tanya would currently be 10 years old. by plugging in 10 for n in n + 5, you would figure out that in 5 years (aka 10 + 5) tanya would be 15.
i hope this helped! have a great day <3
