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

Respuesta :

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

3x +6=126

Answer:

[tex]3x+6=126[/tex]
