Let x represent the first integer, represent the second integer, and represent the third integer.
The sum of these integers would be .
We have been given that the sum of three consecutive even integers is 36. We can represent this information in an equation as:
Combine like terms:
Therefore, the equation can be used find the first integer.
To start this, try to place it all together. (x)+(x+2)+(x+4)=36 Then you start to combine so that it looks like this: 3x+6=36 I believe that is one of the choices. Do you need more explanation?
