Given [ ll x & y+2 3 & z-1 ]= [ ll 3 & 1 3 & 2 ] , Find x, y, z - Vidyadip

Question

Given $\left[\begin{array}{ll}x & y+2 \\ 3 & z-1\end{array}\right]=\left[\begin{array}{ll}3 & 1 \\ 3 & 2\end{array}\right]$ , Find x, y, z

✓

Answer

If two matrices are equal, then their corresponding elements are also equal. Therefore, we have:

x = 3,

y + 2 = 1 ⇒ y = -1

z - 1 = 2 ⇒ z = 3
