3x -12 = 2y
3/2 x - 6 = y
----------------------------
5x+y = 7
y = -5x +7
---------------------------
Mencari titik potong. Maka, y=y
3/2 x - 6 = -5x +7
3x -12 = -10x + 14
3x+10x = 14+12
13 x = 26
x = 2
Mencari y, gunakan salah satu persamaan dan ganti x nya dengan 2
y = -5x + 7
y = -10 + 7
y = -3
Jadi, titik potongnya adalah (2,-3)
B. (2,-3)
