    All I can say is, you have at least two other people taking the exact same class you are.

    i would find x first. then, when i have that answer, i use it to find y. i was taught that way. but maybe your way does work better.

    Originally, you said "divide both sides by x". I was waiting to see how you would use that to solve it.

    I want to see the method where you divide both sides by x only.

    the way i was taught is you find x first. then when you plug in x, you could find y.

    What was that drivel between Durviel and Hero lol...Thought you were supposed to be helping... I will help. So we have: 4x + 7y = 6 and 6x + y = 2 The correct first step is to multiply the second equation by 7 to get: 42x + 7y = 14 We can then eliminate the 7 by subtracting equation 1 (unchanged) from equation 2. :)
