Answer:

$\boxed {s = 14}$

Explanation:

Solve for the value of
:

(2)/(3)s + (5)/(6)s = 21

-Combine like terms:

(2)/(3)s + (5)/(6)s = 21

(3)/(2)s = 21

-Multiply
(2)/(3) on both sides, which is the reciprocal of
(3)/(2) , and multiply
and
:

s = 21 * ((2)/(3))

s = (21 * 2)/(3)

s = (42)/(3)

-Divide
by
:

s = (42)/(3)

$\boxed {s = 14}$

Therefore, the value of
is
