    I hope I'm not annoying you, but I like your explanations, so I'll take the liberty of coming back to ask questions.

    I would like to know how to divide this algebraic expression by the monomial?

    32x2y4z + 46xy32x

    Do you have other numbers to suggest to me as well?

    Thank you.

    Hello! Sorry to bother you again, but I still don't understand this problem.

    I have to do the comparison method with these two equations:

    1 → 3x - y = 18

    2 ⇾ -2y = -6x - 120

    And when I isolated y, it gave me: 

    1 → y = 3x + 60

    2 → y = 3x - 18

    But it doesn't work !!! I came to an unrealistic answer. Can you help me isolate my equations, because I think I made a mistake please. It would help me enormously! Thanks in advance!
