The system of linear equations to solve is:

\[
5x + 4y = 8 \quad \text{(Equation 1)}
\]
\[
10x - 4y = 46 \quad \text{(Equation 2)}
\]

### Step 1: Add the equations
To eliminate \( y \), add both equations:

\[
(5x + 4y) + (10x - 4y) = 8 + 46
\]

Simplifying:

\[
5x + 10x + 4y - 4y = 54
\]

\[
15x = 54
\]

### Step 2: Solve for \( x \)
Now, solve for \( x \) by dividing both sides by 15:

\[
x = \frac{54}{15} = \frac{18}{5}
\]

### Step 3: Substitute \( x \) into one of the original equations
Substitute \( x = \frac{18}{5} \) into Equation 1:

\[
5\left(\frac{18}{5}\right) + 4y = 8
\]

This simplifies to:

\[
18 + 4y = 8
\]

### Step 4: Solve for \( y \)
Now, solve for \( y \):

\[
4y = 8 - 18
\]

\[
4y = -10
\]

\[
y = \frac{-10}{4} = \frac{-5}{2}
\]

### Final Answer:
The solution to the system is:

\[
x = \frac{18}{5}, \quad y = \frac{-5}{2}
\]
