Question

3. Find the value of each variable.x = -1, y = 30x = 4, y = 2Ox = 3, y = -1ox = 2, y = 4

Answer 1

Note that two matrices are said to be equal if they have the same order, and their corresponding elements are also the same.

Given that,

`\begin{bmatrix}{4} & {3} & {} \\ {-1} & 2{} & {}{}\end{bmatrix}=\begin{bmatrix}{4} & {y} & {} \\ {x} & 2{} & {}{}\end{bmatrix}`

Compare the corresponding terms to get,

`\begin{gathered} x=-1 \\ y=3 \end{gathered}`

Thus, the first option is the correct choice.
