Hello and Good Morning/Afternoon

Let's take this problem step-by-step:

To find the solution to a system of equation

⇒ must set the equations equal to each other

⇒ and solve

Let's put that into action

$x^2-2x+3 = -2x + 12\\x^2-2x+2x+3-12=0\\x^2-9=0\\(x+3)(x-3)=0$

At this point, to make the whole thing equal zero

⇒ either 'x+3' or 'x-3' equals zero

⇒ must find 'x' that satisify either equation

$x-3=0\\x=3\\\\x+3=0\\x=-3$

Let's find the corresponding f(x) to each x-value

$f(3) = -2(3)+12=-6+12 = 6\\\\f(-3) = -2(-3) + 12=6+12=18$

Therefore the solutions are (3,6) and (-3,18)

Answer: (3,6), (-3,18)

Hope that helps!

If we plug in 0 for x, we can receive the data for the year 1982. Doing so shows us that the Rural area was 1,417.4 million acres and the total area was 1,839.4 million acres. Therefore, we can conclude that the majority of the area of the United States was rural in 1982.
