Suppose that you wanted to use this row [-2 4 6 | 14] to eliminate as many elements as possible in this row [2 4 -6 1 | 12]; how would you do this?

is this matrix row operations?

Add them. Probably. At least it looks as if the 2s and the 6s will cancel. But. The problem is your two rows aren't compatible: four numbers in the first and five in the second. You're missing a number or have one extra. I suggest you just look at each number to see what you would have to do to cancel it, then see what other numbers will cancel. In reality you NEVER look for "as many elements as possible" it's trying to be too clever, you just do them one at a time.
