Find three consecutive even integers such that twice largest integer exceeds the sum of the sum of the first two by 6.

Step 1. Let n be the first even integer.

Step 2. Let n+2 and n+4 be the next two even integers.

Step 3. Let 2(n+4)=2n+8 be twice the largest integer.

Step 4. Let n+n+2=2n+2 be the sum of the first two.

Step 5. Then, 2n+8=2n+2+6 since twice largest integer exceeds the sum of the sum of the first two by 6.

Step 6. Solving the equation in Step 5 yields the following steps.

DETAILED EXPLANATION


Look at 2%2An%2B8=2%2An%2Bhighlight_red%28+2+%29%2Bhighlight_red%28+6+%29.
Added fractions or integers together
It becomes 2%2An%2B8=2%2An%2Bhighlight_green%28+8+%29.

Look at 2%2An%2B8=highlight_red%28+2%2An%2B8+%29.
Moved these terms to the left highlight_green%28+-2%2An+%29,highlight_green%28+-8+%29
It becomes 2%2An%2B8-highlight_green%28+2%2An+%29-highlight_green%28+8+%29=0.

Look at 2%2An%2Bhighlight_red%28+8+%29-2%2An-highlight_red%28+8+%29=0.
Added fractions or integers together
It becomes 2%2An%2Bhighlight_green%28+0+%29-2%2An=0.

Look at 2%2An%2Bhighlight_red%28+0+%29-2%2An=0.
Moved 0 to the right of expression
It becomes 2%2An-2%2An%2Bhighlight_green%28+0+%29=0.

Look at 2%2An-2%2An%2Bhighlight_red%28+0+%29=0.
Remove extraneous zero highlight_red%28+0+%29
It becomes 2%2An-2%2An=0.

Look at highlight_red%28+2%2An+%29-highlight_red%28+2%2An+%29=0.
Eliminated similar terms highlight_red%28+2%2An+%29,highlight_red%28+-2%2An+%29 replacing them with highlight_green%28+%282-2%29%2An+%29
It becomes highlight_green%28+%282-2%29%2An+%29=0.

Look at highlight_red%28+%282-2%29%2An+%29=0.
Since highlight_red%28+%282-2%29%2An+%29 has zero as a factor, it should be replaced with a zero

Look at 0=0.
Added fractions or integers together
It becomes 0=0.
Result: 0=0

Step 7. ANSWER: The three consecutive integers can be anything that the satisfies equation in Step 5.

For example 2, 4, 6 will yield 2(6)=2+4+6 which is a true statement

Another example, 20, 22, 24 will yield 2(24)=20+22+6 which is another true statement

I hope the above steps were helpful.
