Hello, Debbie! Whenever you see a word problem have a number times another value, write the number, then an open parenthesis symbol. Next, since you do not know the identity of the number, choose a variable, such as x. The word “sum” implies addition, so write a plus sign and the number after the word “and.” Next, write a closed parenthesis symbol. Finally, write the equal sign, since the word “equals” is in the problem, and then the number after the word “equals.”
