If A= (-1 -3 2) (2 5 -1) (-4 -5 -4) and B= (3 3 5) (2 -5 2) (-4 -1 1), find AB

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
