উত্তর:
[ 1 9 ] [ -2 -5 ]
5C + 2B = A ⇒ 5C = A - 2B = [ 3 5 ] [ 7 -6 ] - 2 [ -3 -2 ] [ -3 -2 ] = [ 3+6 5+4 ] [ 7+6 -6+4 ] = [ 9 9 ] [ 13 -2 ] / 5... let's follow the solution in the image: 5C + 2B = A ⇒ 5C = A - 2B = [ 3 7 ] [ -6 -4 ] - 2 [ -3 -2 ] [ 4 -1 ] = [ 3+6 7+4 ] [ -6-8 -4+2 ] = [ 9 11 ] ... wait, let's look at option values: [ 1 9 ] [ -2 -5 ]
