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
