For a system of equations {ax+by=jcx+dy=k ,the coefficient matrix is [abcd] and the augmented matrix is [abjcdk]
a) For the system {8x+3y=253x9y=12a=8,b=3,c=3 and d=9 so the coefficient matrix is [8339]
b) For the system {8x+3y=253x9y=12a=8,b=3,c=3,d=9,j=25 and k=12 so the augmented matrix is [83253912]
