Find x, y, z from Matrix Equation

Finding x, y, z

Question:
Solve: \[ [x,\; y+2,\; z-3] + [y,\; 4,\; 5] = [4,\; 9,\; 12] \]

Solution:

Step 1: Add corresponding elements

\[ [x+y,\; y+6,\; z+2] = [4,\; 9,\; 12] \]

Step 2: Compare corresponding elements

\[ x + y = 4 \quad …(1) \] \[ y + 6 = 9 \Rightarrow y = 3 \quad …(2) \] \[ z + 2 = 12 \Rightarrow z = 10 \quad …(3) \]

Step 3: Substitute value of \(y\)

\[ x + 3 = 4 \Rightarrow x = 1 \]

Final Answer:

\[ x = 1,\quad y = 3,\quad z = 10 \]
