Question

A dog weighs two pounds less than three times the weight of a cat. The dog also weights twenty-two more pounds than the cat. Write and solve an equation to find the weights of the cat and the dog.

Answer 1

3c-2=c+22

The dog weights 34 pound and the cat weights 12 pounds

Explanation:

Answer 2

the cat weighs 21 pounds.

the dog weighs 43 pounds

Explanation:

dog = 3x-20 = x + 22

cat = x

3x-20 = x+22

3x = x+42 (add 20 to both sides)

2x = 42 (subtract x from both sides)

x = 21
