Answer:
x=3, y=-2. (3, -2).
Step-by-step explanation:
4x+2y=8
5x+3y=9
---------------
simplify 4x+2y=8 into 2x+y=4
-----------------
2x+y=4
5x+3y=9
----------------
y=4-2x
5x+3(4-2x)=9
5x+12-6x=9
-x=9-12
-x=-3
x=3
2(3)+y=4
6+y=4
y=4-6
y=-2
This is the process of completing the square.
Keep this equation in mind:

Basically, to make this a perfect square trinomial, you take half of b and square that value. This will make it so you can compress the left side of the equation into

depending on the sign in the middle of the original equation.
