Final answer:
To solve the system of equations, substitute the given value of x into the first equation and solve for y.
Step-by-step explanation:
To solve a system of linear equations, we need to find the values of x and y that satisfy both equations. In this case, we are given the equations y = -x - 6 and x = -4. We can substitute the value of x from the second equation into the first equation, giving us y = -(-4) - 6. Simplifying, we get y = 4 - 6 = -2.
The solution to the system of equations is x = -4 and y = -2.
