Solution Steps
Solution Approach
To solve for \(x, y, z,\) and \(w\), we need to equate the corresponding elements of the two matrices. This will give us a system of equations:
\(x + y = 3\)
\(y + z = 5\)
\(z + w = 5\)
\(w = 2\)
We can solve this system of equations step-by-step to find the values of \(x, y, z,\) and \(w\).
Step 1: Set Up the Equations
We start with the matrix equation given in the problem, which leads to the following system of equations:
\( x + y = 3 \)
\( y + z = 5 \)
\( z + w = 5 \)
\( w = 2 \)
Step 2: Solve for \( w \)
From equation 4, we directly find:
\[
w = 2
\]
Step 3: Substitute \( w \) into the Third Equation
Substituting \( w = 2 \) into equation 3:
\[
z + 2 = 5
\]
This simplifies to:
\[
z = 3
\]
Step 4: Substitute \( z \) into the Second Equation
Now, substituting \( z = 3 \) into equation 2:
\[
y + 3 = 5
\]
This simplifies to:
\[
y = 2
\]
Step 5: Substitute \( y \) into the First Equation
Finally, substituting \( y = 2 \) into equation 1:
\[
x + 2 = 3
\]
This simplifies to:
\[
x = 1
\]
Final Answer
The values of \( x, y, z, \) and \( w \) are:
\[
\boxed{(x, y, z, w) = (1, 2, 3, 2)}
\]
