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

Answer:

$3x+6=126$

Step-by-step 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 $3x+6=126$

Answer 2

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

3x +6=126
