Penjelasan dengan langkah-langkah:
1/3x + 2/5y = 4/15
15(1/3x + 2/5y) = 4
15/3x + 6y = 4 (semua dikalikan 3)
15x + 18y = 12
3/4x - 1/2y = 2 (semua dikalikan 4)
3x - 2y = 8
15x + 18y = 12 | x1 |
3x - 2y = 8 | x5 |
-----------------------------
15x - 10y = 40
---------------------- -
28y = -28
y = -1
3x - 2(-1) = 8
3x + 2 = 8
3x = 6
x = 2
