One solution to the equation a + b + c = 10 is a = 2, b = 5 , c = 3 .
How many different whole-number solutions are there to the equation a + b + c = 10? Explain or show your reasoning.
Here are three situations and six equations. Which equation best represents each situation?
After Elena ran 5 miles on Friday, she had run a total of 20 miles for the week. She ran x miles before Friday.
Andre’s school has 20 clubs, which is five times as many as his cousin’s school. His cousin’s school has x clubs.
Jada volunteers at the animal shelter. She divided 5 cups of cat food equally to feed 20 cats. Each cat received x cups of food.
x + 5 = 20
x = 20 + 5
5x = 20
x + 20 = 5
5 \sdot 20 = x
20x = 5
