  M = (S -C)/C

Step-by-step explanation:

Starting with ...

  S = C + MC

we want to solve for M.

  S - C = MC . . . . subtract the term not containing M

  (S -C)/C = M . . . . divide by the coefficient of M

Solved for M, the formula is ...

  M = (S -C)/C

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
