Can you help me find three consecutive even integers with the sum of-84

Thank you for the opportunity to help you with your question!

Let us call the first even integer x because we do not know what it is yet and so we have to label it as a variable. To get to the next even integer we add 2 to the first number. The second number is thus x+2. We add 2 to the second number to get the last even integer. The third number is x+4. Add all these up and set equal to 84.

x + x+2 + x+4 = 84

3x+6=84    I just combined like terms. Subtract 6 from both sides.

3x=78       Divide both sides by 3.

x= 26

Add 2 to get the next number 28.

Add 2 to 28 to get the last number which is 30.

26,28,30 are the three consecutive even integers that add to 84.



Please let me know if you need any clarification. I'm always happy to answer your questions.
