Answer 3

good morning @mathmate

Answer 4

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.
