In the system below, use equation (1) with equation (2) to eliminate x. Then use equation (1)
with equation (3) to eliminate x.
What is the new 2 x 2 system?
2y - 3z = 12
-3y - 8z=7
2y - 3z = 12
-3y + 8z = 7
2y - 3z = 12
-2y-6z = 3
XY-27=4
x+3y-z=8
(2)
2x-y-4z=-1 (3)
DONE

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
