Question

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

Answer 1

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

Answer 2

Answer:

17

Step-by-step explanation:

11 + 17 = 28

17 - 6 = 11
