2x + 3y + 2z = 3 dieliminasi dg 2x + y + 2z = 5 jadi 2y = -2 y = -1...(1) x + 2y + 3z = 3 x + 2 (-1) + 3z = 3 x - 2 + 3z = 3 x + 3z = 5...(2) 2x + 3y + 2z = 3 2x + 3 (-1) + 2z = 3 2x - 3 + 2z = 3 2x + 2z = 6...(3) x + 3z = 5 dikali 2 ==> 2x + 6z = 10..(4) 2x + 2z = 6 dikali 3 ==> 6x + 6z = 18..(5) (4)&(5) dieliminasi Jadi -4x = -8 x = 2...(6) 2x + 6 z = 10 2(2) = 6z = 10 4 + 6z = 10 6z = 6 z = 1
