The Elimination Method

Simple Mathematics, really. To eliminate one component To solve a problem quickly. I’ll form the problem into a manageable state, By easily eliminating an unwanted variable. Now, just what variable to eliminate? First, I will multiply the X by two. That’s the first step. Done, I feel fine. I will multiply the Y too. Now, I add my X plus X. My Y plus Y. That was to make sure it checks. Now here’s the predicament (easy my shoe!) This is my problem, And a real head-scratcher too! The equation adds up nicely And the X and Y are simplified. But, how do I eliminate my algebra homework Precisely?
