BAGAI MANA MENCARI HASIL 2X+2Y=4 X-Y=10

2x + 2y = 4 (dikali 1) = 2x + 2y = 4 x - y = 10 (dikali 2) = 2x - 2y = 10 2x + 2y = 4 dikurangi 2x - 2y = 10 Hasilnya 4y = -6 Y = -6/4 x - y = 10 X - (-6/4) = 10 x + 6/4 =10 X = 10 - 6/4 = 40/4 - 6/4 = 36/4 = 9 Jadi x= 9 dan y= -6/4 Semoga membantu :)

2x + 2y = 4
x + y = 2
x - y = 10
2x = 12
x = 6
x - y = 10
6 - y = 10
y = 6- 10
y = -4
