To solve the system of equations by substitution, we can start by substituting the value of x from the first equation into the second equation:
x + 5y = 2
(-4y) + 5y = 2
-y = 2
y = -2
Now that we have found the value of y, we can substitute it back into the first equation to find the value of x:
x = -4y
x = -4(-2)
x = 8
Therefore, the solution to the system of equations is (8, -2).
