We have two equations:

y = x ^ 2 + 4x + 3 --- Equation 1
y = 2x + 6 --- Equation 2

We can set the right-hand sides of the two equations equal to each other since they are both equal to y:

x ^ 2 + 4x + 3 = 2x + 6

Subtracting 2x + 6 from both sides, we get:

x ^ 2 + 2x - 3 = 0

We can factor the quadratic equation:

(x + 3)(x - 1) = 0

This gives us two possible solutions:

x + 3 = 0 or x - 1 = 0

Solving for x, we get:

x = -3 or x = 1

Substituting these values back into either Equation 1 or Equation 2, we can solve for y:

When x = -3, y = (-3) ^ 2 + 4(-3) + 3 = 0
When x = 1, y = 2(1) + 6 = 8

Therefore, the solution to the system of equations is (x, y) = (-3, 0) and (1, 8).
