You are hosting a party. you are providing 3 food items. each guest brings 2 food items. write an equation in two variables that represents the total number of food items.

y = 3 + 2x

Step-by-step explanation:

Let y = Total number of food items

Let x = Number of guests

y = 3 + 2x

Example:

If there are 14 guests, we have:

y = 3 + 2(14)

y = 3 + 28

y = 31

So the equation gives us a total number of 31 food items from both you and the guests.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
