Answer:

see explanation

Explanation:

Given

c = (s +
(b)/(3)) m

There are 2 possible approaches

Approach 1

Divide both sides by m


(c)/(m) = s +
(b)/(3)

Multiply both sides by 3 to clear the fraction


(3c)/(m) = 3s + b ( subtract b from both sides )


(3c)/(m) - b = 3s ( divide both sides by 3 )


(3c)/(3m) -
(b)/(3) = s, cancelling the factor 3 gives

s =
(c)/(m) -
(b)/(3)

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

Approach 2

Distribute the right side by m

c = ms +
(bm)/(3)

Multiply through by 3 to clear the fraction

3c = 3ms + bm ( subtract bm from both sides )

3c - bm = 3ms ( divide both sides by 3m )


(3c)/(3m) -
(bm)/(3m) = s, thus

s =
(c)/(m) -
(b)/(3)
