Given the numerical equation:

r = m/2 ( c + k)

Solve for k.

Solution:

In order to solve for k, the first step is to multiply both sides by 2/m which is the inverse or reciprocal of m/2. In this way, we can cancel out m/2.

r = m/2 ( c + k ) 

(2/m) r = m/2 ( c + k ) (2/m)

2r/m = c + k

Transpose c to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

k = (2r/m) - c

Final answer:

k = (2r/m) - c
