To solve the system of equations:

  1. \( 5x - 4y = -44 \) (Equation 1)
  2. \( -x + 3y = 22 \) (Equation 2)

Let's solve this step by step.

First, we can solve Equation 2 for \( x \):

\[ -x + 3y = 22 \implies x = 3y - 22 \]

Now, substitute this expression for \( x \) into Equation 1:

\[ 5(3y - 22) - 4y = -44 \]

Expanding this gives:

\[ 15y - 110 - 4y = -44 \]

Combine like terms:

\[ 11y - 110 = -44 \]

Now, add 110 to both sides:

\[ 11y = 66 \]

Next, divide by 11:

\[ y = 6 \]

Now that we have \( y \), substitute \( y = 6 \) back into the equation for \( x \):

\[ x = 3(6) - 22 \] \[ x = 18 - 22 \] \[ x = -4 \]

Thus, the solution to the system of equations is:

\[ (x, y) = (-4, 6) \]

Therefore, the answer is:

\[ (-4, 6) \]
