What is the solution of the system? y=x^2 + 6x + 9

y = x+3

Because we have two values of x, we can set the two expressions equal to each-other.

x^2 + 6x + 9 = x + 3

Subtract x and 3 from both sides.

x^2 + 5x + 6 = 0

Now that we have all terms on one side, we can find the values of x.

Using the AC method, we can simplify this equation to (x + 2) (x + 3)

The solutions to the system of equations presented are:

x = - 2, x = - 3.
