The sum of three consecutive even integers is 36. 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?

a. 2x + 6 = 36

b. 3x + 6 = 36

c. 3x + 36 = 2x + 6

d. 3x = 2x + 6

Respuesta :

b.
It will give you a value of 10 for x, which is the first integer you should need.
x+2 : 10+2=12
x+4 : 10+4=14
10+12+14=36
