Answer
2.4 -7.6
9 .3
-7.7 1.3
Work Step by Step
In order to subtract matrices, we subtract each number and its corresponding number. Thus, we subtract the two numbers in the upper left corner of the first two matrices and put the difference in the upper left corner of the new matrix. We do the same thing for the numbers in the upper right corner, middle left side, middle right side, lower left corner, and lower right corner. Thus, we obtain the answer:
2.4 -7.6
9 .3
-7.7 1.3
