    solve for M means "get M alone on one side" of the equal sign

    what do you get when you solve for M in this: M+3n=7n

    ok so to solve for M in M+3n=7n you have to leave M by itself M=7n-3n then once you have M by itself you can plug in what you got for M then solve 7n-3n+3n=7n everything cancels out therefore it means that it is exact opposite

    ok now plug in what you got for M you end up with 7n-3n+3n=7n

    \(M+3n=7n\) Subtract 3n on both sides. What would you get?

    Hang on. It is \(m+3n=7\) and \(n=-2, 0, 1\) correct?

    I don't get you. You said yes, then you contradicted me and said \(7n\). AGAIN, is it only 7 or \(7n\)?
