MCQ

If $\left[\begin{array}{cc}x & 3 x-y \\ z x+z & 3 y-w\end{array}\right]=\left[\begin{array}{ll}3 & 2 \\ 4 & 7\end{array}\right]$, then

✓
x = 3, y = 7, z = 1, w = 14
B
x = 3, y = -5, z = -1, w = -4
C
x = 3, y = 6, z = 2, w = 7
D
x = -3, y = -7, z = -1, w = -14

✓

Answer

Correct option: A.

x = 3, y = 7, z = 1, w = 14

x = 3, y = 7, z = 1, w = 14
