Question

Which matrix is equal to P+Q? P Р 6.1 1.9 -7.5 2.2 3.8 -1.4 and Q -7.2 7.6 1.8 -1.4 2.3 2.1 1.1 9.5 --5.7 0.8 6.1 0.7] 13.3 -5.71 -9.3 3.6 1.5 -3.5 1.1 -9.5 5.7 -0.8 -6.1 -0.7I'll send a picture of problem

Answer 1

$P+Q=\begin{bmatrix}{6.1} & {1.9} & {} \\ {-7.5} & {2.2} & {} \\ {3.8} & {-1.4} & \end{bmatrix}+\begin{bmatrix}{-7.2} & {7.6} & {} \\ {1.8} & {-1.4} & {} \\ {2.3} & {2.1} & \end{bmatrix}$$\begin{bmatrix}{6.1-7.2} & {1.9+7.6} & {} \\ {-7.5+1.8} & {2.2-1.4} & {} \\ {3.8+2.3} & {-1.4+2.1} & \end{bmatrix}$$P+Q=\begin{bmatrix}{-1.1} & {9.5} & {} \\ {-5.7} & {0.8} & {} \\ {6.1} & {0.7} & \end{bmatrix}$
