Math Problem Statement
Find the value in row 2 column 1 of A + B, where A and B are given matrices.
Solution
Let's solve the given problem!
The task is to calculate the value in row 2, column 1 of the matrix , where:
1 & 3 & 5 \\ 5 & -1 & 1 \\ 3 & 0 & -2 \end{bmatrix}, \quad B = \begin{bmatrix} 3 & -5 & 2 \\ 3 & 4 & 0 \\ 2 & 1 & -3 \end{bmatrix}.$$ ### Step 1: Add the corresponding elements of matrices $$A$$ and $$B$$. Matrix addition involves adding corresponding elements. For row 2, column 1: $$(A + B)_{2,1} = A_{2,1} + B_{2,1}.$$ From $$A$$, $$A_{2,1} = 5$$. From $$B$$, $$B_{2,1} = 3$$. $$(A + B)_{2,1} = 5 + 3 = 8.$$ ### Final Answer: The value in row 2, column 1 of $$A + B$$ is **8**.
