The sum of two numbers is 27. One of the numbers is three more than the other. Find the numbers.

Answer 1

Let F = the first number

F + 3 = the second number

27 = the sum of the two numbers

F + (F + 3) = 27

2F + 3 = 27

2F = 24

F = 12

F + 3 = 12 + 3 = 15

ANSWER: THE TWO NUMBERS ARE 12 AND 15.

Hope this was helpful RUBI.

Answer 2

a + b = 27

a = b + 3

We can substitute terms and expressions on either side of the =, since they are equal.

b + 3 + b = 27

2b + 3 - 3 = 27 - 3

2b/2 = 24/2

b = 12

a = 12 + 3

a = 15

The two numbers are 12 and 15.

Answer 3

Let "n" be one of the numbers. We are told that the other number is three more than "n" so it must be "n + 3". We are also told that the sum of the numbers "n" and "n + 3" is 27. So we can write:

n + n + 3 = 27 [now we can combine like-terms like this:

2n + 3 = 27 [now we can subtract 3 from both sides to get this:

2n = 24 [now we can divide both sides of the equation by 2 to get this:

n = 12

So the first number is 12 and the other number is three more or 15.
