<h2>(x, y) = (x, 2 + 5/6 x)</h2>
Step-by-step explanation:
-5x + 6y = 12
y = 5/6x + 2
<h2>_______________</h2>
-5x + 6y = 12
-5x + 6(5/6x + 2) = 12
-5x + 5x + 12 = 12
x real numbers
(x, y) = (x, 2 + 5/6 x)
The other two options are (x -5) or (x + 1).
The best way to go about finding this is by dividing. You can do this through synthetic division or by long division.
After dividing by x + 3, you'll be left with x^2 - 4x - 5, which can be factored. To factor, always check factors of the last number that add to the middle number. The factors of -5 are either 1 and -5 or 5 and -1. Since the first pair add to the middle coefficient, use those in the parenthesis.
