From the image you uploaded, the given matrix equation is:

\[
\begin{bmatrix} 
2 & 4x \\ 
x + 3y & 5y + 10z 
\end{bmatrix} 
- 
\begin{bmatrix} 
8 & 3 \\ 
4 & 5 
\end{bmatrix} 
= 
\begin{bmatrix} 
8 & 5 \\ 
9 & -15 
\end{bmatrix}
\]

We can solve this matrix equation step by step.

### Step 1: Subtract the matrices

First, subtract the matrix \(\begin{bmatrix} 8 & 3 \\ 4 & 5 \end{bmatrix}\) from the matrix \(\begin{bmatrix} 2 & 4x \\ x + 3y & 5y + 10z \end{bmatrix}\):

\[
\begin{bmatrix} 
2 - 8 & 4x - 3 \\ 
(x + 3y) - 4 & (5y + 10z) - 5 
\end{bmatrix}
=
\begin{bmatrix} 
8 & 5 \\ 
9 & -15 
\end{bmatrix}
\]

Simplifying:

\[
\begin{bmatrix} 
-6 & 4x - 3 \\ 
x + 3y - 4 & 5y + 10z - 5 
\end{bmatrix}
=
\begin{bmatrix} 
8 & 5 \\ 
9 & -15 
\end{bmatrix}
\]

### Step 2: Set up the system of equations

Now, equate the corresponding elements of the matrices:

1. \(-6 = 8\) (This equation has no solution and suggests there may be a mistake or contradiction.)
2. \(4x - 3 = 5\)
3. \(x + 3y - 4 = 9\)
4. \(5y + 10z - 5 = -15\)

### Step 3: Solve the system of equations

#### For the second equation:
\[
4x - 3 = 5
\]
Add 3 to both sides:
\[
4x = 8
\]
Divide by 4:
\[
x = 2
\]

#### For the third equation:
Substitute \(x = 2\) into the equation \(x + 3y - 4 = 9\):
\[
2 + 3y - 4 = 9
\]
Simplify:
\[
3y - 2 = 9
\]
Add 2 to both sides:
\[
3y = 11
\]
Divide by 3:
\[
y = \frac{11}{3}
\]

#### For the fourth equation:
Substitute \(y = \frac{11}{3}\) into the equation \(5y + 10z - 5 = -15\):
\[
5\left(\frac{11}{3}\right) + 10z - 5 = -15
\]
Simplify:
\[
\frac{55}{3} + 10z - 5 = -15
\]
Multiply everything by 3 to eliminate the fraction:
\[
55 + 30z - 15 = -45
\]
Simplify:
\[
30z + 40 = -45
\]
Subtract 40 from both sides:
\[
30z = -85
\]
Divide by 30:
\[
z = \frac{-85}{30} = \frac{-17}{6}
\]

### Final Answer:
- \(x = 2\)
- \(y = \frac{11}{3}\)
- \(z = \frac{-17}{6}\)
