Berapa hasil -6= 2x-3y
y= x²+4x+3..

#F

-6= 2x-3y
→ 3y = 2x + 6

y = 2/3 x + 2

y= x²+4x+3 → (2/3)x + 2 = x²+4x+3

2x + 6 = 3x² + 12x + 9

3x² +12x – 2x + 9 – 6 = 0

3x² +10x + 3 = 0

(3x + 1)(x + 3) =0

x = -1/3 ∨ x = – 3

nilai y adalah y = 2/3 x + 2

jika x = – 1/3 , maka y = 2/3 (-1/3) + 2 = – 2/9 + 2 = 16/9

jika x = -3 , maka y = 2/3(-3) + 2 = 0

HP (x,y) ={(-1/3, 1`6/9) , (-3, 0)}
