    Solution for the given fractions

    • (-5*x)/7 + 10/21 = ?
    • The common denominator of the two fractions is: 21
    • (-5*x)/7 = (-5*3*x)/(3*7) = (-15*x)/21
    • 10/21 = (1*10)/(1*21) = 10/21
    • Fractions adjusted to a common denominator
    • (-5*x)/7 + 10/21 = (-15*x)/21 + 10/21
    • (-15*x)/21 + 10/21 = (10-15*x)/21
    • (10-15*x)/21 = (10-15*x)/21

    Solution for the given fractions

    $ \frac{(-5*x)}{7 }+\frac{ 10}{21 }=? $

    The common denominator of the two fractions is: 21

    $ \frac{(-5*x)}{7 }= \frac{(-5*3*x)}{(3*7)} = \frac{(-15*x)}{21} $

    $ \frac{10}{21 }= \frac{(1*10)}{(1*21)} =\frac{ 10}{21} $

    Fractions adjusted to a common denominator

    $ \frac{(-5*x)}{7 }+\frac{ 10}{21 }= \frac{(-15*x)}{21 }+\frac{ 10}{21} $

    $ \frac{(-15*x)}{21 }+\frac{ 10}{21 }= \frac{(10-15*x)}{21} $

    $ \frac{(10-15*x)}{21 }= \frac{(10-15*x)}{21} $

    $ $
