Josh has two dogs. The larger dog weighs 1.4 pounds more than the smaller dog. The combined weight of the two dogs is 12.6 pounds

Let s = the weight of the smaller dog

Which equation could be used to solve for the weight of the smaller dog?

• (s) + (s + 1.4) = 12.6

• (s) + (s - 1.4) = 12.6

• (s)(s + 1.4) = 12.6

• (s) - (s + 1.4) = 12.6
