    2/5x + 7 = 10 - 1/6x


    Change fractions to a common denominator, then rewrite problem.


    12/30x + 7 = 10 - 5/30x


    12/30x + 5/30x  +7 -7 = 10 -7 - 5/30x + 5/30x


    Or,


    12/30x + 7 = 10 - 5/30x


    +5/30x   -7  = -7   +5/30x


    -------------------------------------


    17/30x = 3


    +7 and -7, -5/30x and +5/30x, cancels out.


    17/30x = 3


    Divide 17/30 on both sides.


    x = 3 / 17/30


    Take the reciprocal


    x = 3 * 30/17


    x = 90/17
