To solve the system of equations

\[ -4x + 6y = 38 \quad (1) \] \[ x - 5y = -20 \quad (2) \]

we can use substitution or elimination. Here, we will use substitution.

From equation (2), we can express \( x \) in terms of \( y \):

\[ x = 5y - 20 \]

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

\[ -4(5y - 20) + 6y = 38 \]

Distributing \(-4\):

\[ -20y + 80 + 6y = 38 \]

Combine like terms:

\[ -20y + 6y + 80 = 38 \] \[ -14y + 80 = 38 \]

Now isolate \( y \):

\[ -14y = 38 - 80 \] \[ -14y = -42 \]

Dividing both sides by \(-14\):

\[ y = 3 \]

Now substitute \( y \) back into the expression we found for \( x \):

\[ x = 5(3) - 20 \] \[ x = 15 - 20 \] \[ x = -5 \]

Thus, the solution to the system is:

\[ (x, y) = (-5, 3) \]

The correct response is:

\[ \boxed{(-5, 3)} \]
