Final answer:
The solution to the system of equations is x = -2 and y = 1, found by substituting x = -2 into the first equation y = x + 3.
Step-by-step explanation:
To determine the solution to the system of equations, we can substitute the value of x from the second equation into the first equation. The first equation y = x + 3 becomes y = (-2) + 3 when we substitute x = -2.
Now, we simply calculate the value of y:
y = (-2) + 3y = 1
Thus, the solution to the system of equations is x = -2 and y = 1.
