Answer 1

To determine the number of solutions for the given system of linear equations, we need to analyze the equations:

1. \( x + 2y = -44 \) (Equation 1)
2. \( -x + 8y = -16 \) (Equation 2)

Let's manipulate the equations step by step.

### Step 1: Rearranging Equation 2

We can rearrange Equation 2 to a more standard form:

\[
-x + 8y = -16 \implies x = 8y + 16
\]

### Step 2: Substitute Equation 2 into Equation 1

We can substitute \( x \) from Equation 2 into Equation 1:

\[
(8y + 16) + 2y = -44
\]

### Step 3: Combine the terms

Combine like terms:

\[
8y + 2y + 16 = -44 \implies 10y + 16 = -44
\]

### Step 4: Solve for y

Now, isolate \( y \):

\[
10y = -44 - 16 \implies 10y = -60 \implies y = -6
\]

### Step 5: Find x using y

Now that we have \( y = -6 \), we can find \( x \) using the expression for \( x \) derived from Equation 2:

\[
x = 8(-6) + 16 = -48 + 16 = -32
\]

### Conclusion

We found \( y = -6 \) and \( x = -32 \). This indicates that there is one unique solution to the system of equations:

\[
(x, y) = (-32, -6)
\]

Thus, the answer is:
