To solve the system of equations:
1. \( 5x - 4y = -44 \) (Equation 1)
2. \( -x + 3y = 22 \) (Equation 2)
Let's use the substitution or elimination method to solve this system.
### Step 1: Solve one equation for one variable
From Equation 2, solve for \( x \):
\[
-x + 3y = 22
\]
\[
-x = 22 - 3y
\]
\[
x = 3y - 22 \quad \text{(Equation 3)}
\]
### Step 2: Substitute Equation 3 into Equation 1
Substitute (Equation 3) into Equation 1:
\[
5(3y - 22) - 4y = -44
\]
Distribute the 5:
\[
15y - 110 - 4y = -44
\]
Combine like terms:
\[
11y - 110 = -44
\]
Add 110 to both sides:
\[
11y = 110 - 44
\]
\[
11y = 66
\]
Divide by 11:
\[
y = 6
\]
### Step 3: Substitute \( y \) back to find \( x \)
Now use the value of \( y \) in Equation 3:
\[
x = 3(6) - 22
\]
\[
x = 18 - 22
\]
\[
x = -4
\]
### Step 4: Write the solution
The solution to the system of equations is:
\[
(x, y) = (-4, 6)
\]
### Final Answer
\((-4, 6)\)
