1. Jawaban Arkan5283
3x + y = 1
2x + 3y = 17
3x + y = 1
y = 1 - 3x
2x + 3y = 17
2x + 3(1 - 3x) = 17
2x + 3 - 9x = 17
- 7x = 17 - 3
- 7x = 14
x = 14/-7
x = - 2
y = 1 - 3x
y = 1 - 3(- 2)
y = 1 + 6
y = 7

3x + y = 1
y = -3x + 1
2x + 3y = 17
2x + 3(-3x + 1) = 17
2x - 9x + 3 = 17
2x - 9x = 17 - 3
-7x = 14
x = 14/-7
x = -2
y = -3x + 1
y = -3(-2) + 1
y = 6 + 1
y = 7
HP = { -2, 7 }
