We can set the 2nd equation to y that way we have something to solve for
First we solve our first equation by moving the one to the other side
Then we divide by 3 on each side
So now we can plug 4 into the x's of the 2nd equation
One hundred million, three million, seven hundred twenty seven thousand, four hundred ninety five.
Quadratic formula = (-b +- sqrt(b^2 - (4ac))) / 2a
and
then simplify and solve
Got my answer of what....
