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?

Equation used:

x + x + 2 + x + 4 = 72

x = 22

Step-by-step explanation:

The sum of three consecutive even integers is 72.

First integer = x

Second integer = x+2

Third integer = x + 4

According to question, sum of all three even integers is 72

Therefore,

x + x + 2 + x + 4 = 72   (This equation is used to find x)          

               3x + 6 = 72

                     3x = 66

                       x = 22

Hence, The first equation is 22.
