    Hint by example: If the question were: Write the expression for "the \(\color{blue}{sum}\) of a number and 17" I could write Let x = the unknown number, and the expressions are: x+17, or 17+x The reason we can write it in these two different ways is because addition (+) is commutative. The results are the same if we wrote 5+3 or 3+5. So therefore x+17 and 17+x would both be correct for the required expressions.

    what would the phrase "Twice the sum of a number and three "look like as a variable expression>

    ok the phrasing of the question is slightly ambiguous but you could either have 2n+ 3 or 2(n+3)

    with words functions like these get complicated hence the need for variable expressions as you call them
