The sum of three consecutive even integers is 72. 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 + 6 = 72 3x = 2x + 6 2x + 64 = 72 3x + 72 = 2x + 6

Answer: 3x + 6 = 72

Step-by-step explanation: Three consecutive even integers can be represented as followed.

X → first integer

X + 2 → second integer

X + 4 → third integer

Since the sum of our three consecutive integer is 72, we can set up an equation to represent this.

X + X + 2 + X + 4 = 72

Now, we can simplify on the left.

3x + 6 = 72

Therefore, 3x + 6 = 72 would be the equation.
