SUMMARY

The discussion centers on solving the equation for two consecutive even integers, defined as x and x + 2. The equation derived is 3x = 2(x + 2) - 4. Participants confirm that the equation is valid, leading to the solution where x equals 0, resulting in the integers 0 and 2. There is contention regarding the wording of the problem, with suggestions that it may have intended to include "4 more" for clarity.

Three times the smaller of two consecutive EVEN integers IS four less than twice the larger. What are the two integers?

My set up:

x and x + 2 are the two consecutive even integers. True?

Here, x is the smaller integer and (x + 2) the bigger integer. True?

The equation is 3x = 2(x + 2) - 4. Yes?

Yup. And make sure that x is even. I don't recall if I made a previous comment to you or someone else... If you like you can set x = 2n in your equations and you will come up with a solution that has to be even. But there is no requirement to do so.

No.
3x = 2x + 4 - 4
3x = 2x

Something's wrong with the problem itself...

Why? 3x- 2x= x= 0 is a perfectly valid solution. 0 is an even number, the next even number is 2, 3 times 0 is 0, 2 times 2 minus 4 is also 0.
 
Ok ok...you really think 0 was intended?

Betya a Canadian Loonie that "4 more" was intended :)
 
Is my equation right or wrong?
 
It's right for the way the problem is worded.

But I think the problem is not worded correctly.
 
My set up:

x and x + 2 are the two consecutive even integers.

Here, x is the smaller integer and (x + 2) the bigger integer.

The equation is 3x = 2(x + 2) - 4.

3x = 2(x + 2) - 4

3x = 2x + 4 - 4

3x = 2x

3x - 2x = 0

x = 0

One of the integers is 0 and the other is 0 + 2 or 2.
