Question

The combined weight of a puppy and its mother is 47 pounds. The mother weighs 8 pounds less than 4 times the weight of the puppy. How much does the puppy weigh?​

Answer 1

11 pounds

Explanation:

Let n be the weight of the puppy then the weight of the mother would be...

4n-8

Now we can set up an equation...

4n-8+n=47

Combine like terms

5n-8=47

Add 8 to both sides

5n=55

Divide both sides by 5

n=11

The puppy weighs 11 pounds
