The sum of three consecutive even integers is 36. Let x represent the first integer, x + 2 represent the second integer, and x +
4 represent the third integer.
Which equation can be used to find the first integer?
3x = 2x + 6
2x + 6 = 36
3x + 6 = 36
3x + 36 = 2x + 6

Answer:
C. 
Step-by-step explanation:
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
