Tolong bantu kak.. 😭🙏

5x + 6y = 28xy...(i) -6x + 7y = 9xy...(ii) 1. Mencari nilai x menggunakan metode eliminasi 5x + 6y = 28xy |×6| 30x + 36y = 168xy -6x + 7y = 9xy |×5| -30x + 35y = 45xy __________________ - 71y = 213xy 71y/y = 213x 71 = 213x x = 71/213 x = ⅓ 2. Substitusikan nilai x ke persamaan (ii) -6x + 7y = 9xy -6 (⅓) + 7y = 9 (⅓)y -2 + 7y = 3y 7y - 3y = 2 4y = 2 y = 2/4 y = ½ 3. Substitusikan nilai x dan y 6x + 4y = 6 (⅓) + 4 (½) 6x + 4y = 2 + 2 6x + 4y = 4 (B)
