Solve the system by substitution.

minus, 4, x, plus, 7, y, equals, minus, 41

−4*x*+7*y*=

−41

x, equals, y, plus, 5

*x*=

*y*+5

To solve this system of equations by substitution, we are given the two equations:

1. \(-4x + 7y = -41\)
2. \(x = y + 5\)

### Step 1: Substitute \(x = y + 5\) into the first equation
We can substitute the expression for \(x\) from the second equation into the first equation:

\[
-4(x) + 7y = -41
\]
Substitute \(x = y + 5\):

\[
-4(y + 5) + 7y = -41
\]

### Step 2: Simplify the equation
Now expand the terms:

\[
-4y - 20 + 7y = -41
\]

Combine like terms:

\[
3y - 20 = -41
\]

### Step 3: Solve for \(y\)
Add 20 to both sides of the equation:

\[
3y = -41 + 20
\]
\[
3y = -21
\]

Now, divide by 3:

\[
y = \frac{-21}{3} = -7
\]

### Step 4: Substitute \(y = -7\) back into the equation \(x = y + 5\)
Now that we have \(y = -7\), substitute this value into the second equation \(x = y + 5\):

\[
x = -7 + 5 = -2
\]

### Final Answer:
The solution to the system is:
\[
x = -2, \quad y = -7
\]
