First you add a one under the 45 than multiply the two numerators together than you should get 315 then multiply the two bottoms numbers now your answer should be 315/9 after that you divide 315 and 9 And than make that a mixed fraction and simply if needed
X= -3B + 2A
= [ 9 21 ] + [ 8 -2 ]
-21 -3 10 4
comparing the corresponding elements,
X= [ 9+8 21-2]
-21+10 -3+4
X= [17 19 ]
-11 1
