C.x -3y = 12
x = 3
y = -5
opsi A
y = -4x + 7
-5 = -4(3) + 7
-5 = -12 + 7
-5 = -5
opsi B
3y - 2x +21 = 0
3(-5) - 2(3) + 21 = 0
-15 - 6 + 21 = 0
-21 + 21 = 0
0 = 0
Opsi C
x - 3y = 12
3 - 3(-5) = 12
3 + 18 = 12
21 = 12
Opsi D
2y = -x - 7
2(-5) = -3 - 7
-10 = - 10
hanya opsi C persamaan nya tidak sama karena 21 ≠ 12 jadi jawabannya C.x - 3y = 12
