Penjelasan dengan langkah-langkah:
2. 3x + 2y = -4 | x2 | 6x + 4y = -8
2x - 5y = -28 | x3 | 6x - 4y = -84 -
19y = 76
y = 76 : 19
= 4
3x + 2y = -4 | x5 | 15x + 10y = -20
2x - 5y = -28 | x2 | 4x - 10y = -56 +
19x = -76
x = -76 : 19
= -4
Hp = {-4,4}
3. -2x + 3y = -15 | x5 | -10x + 15y = -75
5x + 8y = -9 | x2 | 10x + 16y = -18 +
31y = -93
y = -93 : 31
= -3
5x + 8y = -9
5x + 8(-3) = -9
5x - 24 = -9
5x = -9 + 24
5x = 15
x = 15 : 5
= 3
Hp = {3,-3}
