Question

The sum of three consecutive even integers is 126. 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

3x + 126 = 2x + 6

2x + 6 = 126

3x + 6 = 126

Answer 1

x = 1x
1x + 1x+ 2 +1x + 4 = 126
rearrange
1x+1x+1x+2+4=126
3x+6=126

3x +6=126

Answer 2

`3x+6=126`

Explanation:

Let x represent the first even integer

Let x + 2 represent the second even integer

Let x + 4 represent the third even integer

Now we are given that The sum of three consecutive even integers is 126.

ATQ

`x+x+2+x+4=126`

`3x+6=126`

So, Option D is correct.

So, equation can be used to find the first integer is
`3x+6=126`
