John has 6 more dogs than Carlota. Together they have 28 dogs. How many dogs does John have?

Answer: John has 17 dogs.

Step-by-step explanation:

Lets start by giving each of the names a variable, so John will be J and Carlota will be C. Then let's write out the equations that are given to us.

The first sentence says "John has 6 more dogs than Carlota."

J = 6 + C

The second sentence says "Together they have 28 dogs."

J + C = 28

Now, we can substitute the first equation in the second one.

(6 + C) + C = 28

And solve!

6 + C + C = 28

2C + 6 = 28

2C = 22

C = 11

Knowing that Carlota has 11 dogs, we can substitue that back into the first equation to get:

J = 6 + 11 = 17

17

Step-by-step explanation:

11 + 17 = 28

17 - 6 = 11
