part 1of3
to solve the problem let x represent

2 + X = 16                  X = 14

Step-by-step explanation:

Try to make X alone so subtract 2 but you also have to subtract the 16 because the equation has to be equal so the answer is 14

14 of the 16 guests left when the party ended, and 2 stayed behind to help.

Step-by-step explanation:

Let's identify what we know:

1) A total of 16 people attended

2) Only 2 stayed behind the help clean up.

We can create a formula, where x represents the number of people that left immediately after the party ended.

16 - 2 = x

x = 14

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
