Answer: x = -1 and y = 9

Explanation:

To solve this system of equations, we can use the substitution method.

First, solve the first equation for y:

y = -x + 8

Now, substitute this expression for y into the second equation and solve for x:

4x + y = 5

4x + (-x + 8) = 5 (substituting -x + 8 for y)

3x + 8 = 5

3x = -3

x = -1

Now that we have found the value of x, we can substitute it back into one of the original equations to solve for y. Let's use the first equation:

y = -x + 8

y = -(-1) + 8

y = 9

Therefore, the solution to the system of equations is x = -1 and y = 9.
