What is the value of the x variable in the solution to the following system of equations?
3x + 2y = 8
2x + 3y = 2

(a)4
(b)−2
(c)x can be any number as there are infinitely many solutions to this system. (d)there is no x value as there is no solution to this system.

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
