If $\left[\begin{array}{ccc}3 & 2 x+5 y & -2 \\ x+4 y & 7 & -5\end{array}\right]=\left[\begin{array}{rrr}3 & 10 & -2 \\ 2 & 7 & -5\end{array}\right]$. Then the values of x and y are: |
$x=-2, y=6$ $x=12, y=5$ $x=-4, y=7$ $x=10, y=-2$ |
$x=10, y=-2$ |
The correct answer is Option (4) - $x=10, y=-2$ |
