Question

Maria has 3 red pens. The rest of her pens are purple. She puts all of her pens into 2 holders. She puts 6 pens in each holder. Which equation can be used to find the number of purple pens?

Answer 1

(6 x 2) - 3 = P

3 red pens - 12 total pens = 9 purple pens

(6 x 2) - 3 = P

p = # of purple pens
