Jamal uses the steps below to solve the equation 6x  – 4 = 8.step 1: 6x  – 4 + 4 = 8 + 4step 2: 6x  + 0 = 12step 3: 6x  = 12step 4:     =  step 5: 1x  = 2step 6:   x  = 2

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
