Penjelasan dengan langkah-langkah:
3x - 2y = 1|×2|6x - 4y = 2
2x + y = 4 |×3|6x + 3y = 12
_________ _
-7y = 14
y = -2
2x + y = 4
2x + -2 = 4
2x = 4 + 2
2x = 8
x = 4
Jawaban:
Hp = {-9, 22}
Penjelasan dengan langkah-langkah:
2x + y = 4
y = 4 - 2x
2y = 2(4 - 2x)
2y = 8 - 4x
3x - 2y = 1
3x - 8 - 4x = 1
3x - 4x = 1 + 8
-x = 9
x = -9
nilai y:
y = 4 - 2x
y = 4 - 2(-9)
y = 4 + 18
y = 22
