Math Problem Statement
Find the value of k
If [16 8 26; 6 3 9; 2 1 4] = [1 2 5; 2 K 0; 7 14 9], find the value of K.
Solution
To find the value of in the equation involving matrices, we need to follow matrix equality principles. The equation given is:
16 & 8 & 26 \\ 6 & 3 & 9 \\ 2 & 1 & 4 \end{bmatrix} = \begin{bmatrix} 1 & 2 & 5 \\ 2 & K & 0 \\ 7 & 14 & 9 \end{bmatrix}$$ For two matrices to be equal, corresponding elements in both matrices must be equal. So, we equate the elements at the same positions in the matrices. Let's focus on the element in the second row and second column (position (2,2)): From the left matrix: $$3$$ From the right matrix: $$K$$ Therefore, $$K = 3$$. So, the value of $$K$$ is: $$K = 3$$ Let me know if you need further clarification! Here are 5 related questions: 1. How do you add two matrices together? 2.
