    Solving Equations

    I have two problems from my Algebra 2 textbook that I was given. They were A & B two-part problems. I'll only give you the first one, if you can show me how it is done, I'll then see if I can see if I can start-finish the second one on my own. Thank you.

    I thank you very much if you can help me out.

    All a least common multiple is, is the smallest number that you can find that numbers will go into. In this problem, It's the same as find the common demnominator, except that you are finding the smallest common denominator.

    21 is the LCM and a common denominator, therefore,

    \frac{7m}{21}+\frac{3m}{21}=1

    \frac{10m}{21}=1

    10m=21

    m=\frac{21}{10}

    I like weezer too!
