Question

Which one is the value for x, y and z

Answer 1

Option (3)

Explanation:

Properties of the equal matrices,

1). Every element of the one matrix are equal to the elements of other.

2). Both the matrices have same dimensions.

If,
`\begin{bmatrix}x+3 & y+4\\ 7 & -5\end{bmatrix}=\begin{bmatrix}5 & 0\\ 7 & z\end{bmatrix}`

`x+3=5`

`x=2`

`y+4=0`

`y=-4`

`x=-5`

Therefore, Option (3) will be the correct option.
