Now, if they are consecutive even numbers, then we know that x is 2 less than y, and y is 2 less than z:
We'll rearrange the second one to be consistent:
Now for the rest of the question. The first number plus the third number is 22 less than the second number multiplied by 3:
To work out the numbers, we will need to substitute the first 2 equations into the third, like this:
Expanding the brackets gives:
Adding 22 to both sides, and taking away 2y from both sides:
So the middle number is 22. Since the other numbers are the even numbers either side of it, the final answer is:
The 3 numbers are 20, 22 and 24.
