Equations from word problems

Let's set the variable x defined as follows:

x = The first even integer

The next even integers are x + 2, x+4, and x+6.

The sum of all of them is 68, thus:

x + x + 2 + x + 4 + x + 6 = 68

Simplifying:

4x + 12 = 68

Subtracting 12:

4x = 68 - 12

4x = 56

Dividing by 4:

x = 56 / 4

x = 14

Thus, the consecutive even numbers are 14, 16, 18, and 20

It can be checked their sum is 68 as required
