tolong bantu yaa, sertakan caranya tentukan hp sistem persamaan brkt. X² + Y² = 16 9x² - 4y² = 36 tolong dibantuuuuu. trimakasih

Hello Trzhaf...

x² + y² = 16
y² = 16 - x²

9x² - 4y² = 36
9x² - 4(16 - x²) = 36
13x² - 64 = 36
13x² = 64 + 36
x² = 100/13
x = ± √(100/13)
x = ± 10/13 √13

x1 = 10/13 √13
x2 = -10/13 √13

y² = 16 - x²
y² = (16 × 13 - 100)/13
y² = 108/13
y = ± 6/13 √39

y1 = 6/13 √39
y2 = -6/13 √39

HP (x,y) = {(x1,y1) , (x1,y2) , (x2,y1) , (x2,y2)}
