Gunakan metode eliminasi 2x – 3y = 3 dan -2x +y =-1
Jawaban Terkonfirmasi
2x-3y=3
-2x+y=-1
________ +
-2y=2
y=-1
2x-3y=3 |x1 ⇒ 2x-3y=3
-2x+y=-1 |x3 ⇒ -6x+3y=-3
__________ +
-4x=0
x=0
2x – 3y = 3 | 1 | 2x – 3y = 3
-2x + y = -1 | -1 | 2x – y = 1 –
– 4y = 4
y = -4/4
y = -1
-2x + y = – 1
-2x + ( -1 ) = -1
-2x = – 1 – ( – 1 )
-2x = – 1 + 1
-2x = 0
x = 0
