Find three consecutive even integers

Question

 Find three consecutive even integers such that the sum of 3 times the first, two times the second, and the largest is 140.

Answer 1

The 3 consecutive even integers are

 

n

n + 2

n + 4

 

The wording of the question translates into

 

3n + 2(n + 2) + (n + 4) = 140

 

Solve for n, and get n + 2 and n + 4.

 

By the way, the title says even integers, but the description just says integers.  These need to say the same thing.

 

 

Answer 2

The three consecutive integers are:

n, n + 1, and n + 2

 

3n + 2(n + 1) + (n + 2) = 140

 

Can you solve for n and answer?

Answer 3

3x + 2(x + 2) + x + 4 = 140

 

I bet you can get it from here.
