What is the equation for the the following: Seven times a number is 32 more than three times that number.

Answer 1

Hi. Let's use the letter "x" to represent the number we don't know.

7x = 3x + 32

Now we can solve for x:

7x = 3x + 32

4x = 32

x = 8

Let's see if we are right:

7(8) = 3(8) + 32

56 = 24 + 32

56 = 56

We are right. The number is 8.
