Math Problem Statement

Determine the values of a and b from the following matrix equation: \[ \begin{pmatrix} 0 & 3 \\ 2b & 4 \end{pmatrix} = \begin{pmatrix} 1 & 3 \\ 4 & a \end{pmatrix} \]

Solution

The problem asks to determine the values of aa and bb based on a matrix equation. The equation shown is:

-0 & 3 \\ 2b & 4 \end{pmatrix} = \begin{pmatrix} 1 & 3 \\ 4 & a \end{pmatrix}$$ To solve this, we need to equate corresponding elements of the two matrices. From the top left corner: $$0 = 1 \quad \text{(This seems like an error in the matrix)}$$ From the top right corner: $$3 = 3 \quad \text{(This is correct)}$$ From the bottom left corner: $$2b = 4 \quad \Rightarrow \quad b = 2$$ From the bottom right corner: $$4 = a \quad \Rightarrow \quad a = 4$$ Thus, the values are: - $$a = 4$$ - $$b = 2$$ Let me know if you need further clarification, or if you'd like more details about matrix equality and how to solve these problems! --- Here are 5 follow-up questions to deepen your understanding: 1.
