2x+y=4
6x-8=1
Jawab sesuai metode eliminasi mencari variabel x dan variabel y
Jawaban :
1). Mencari y
6x - 8y = 1 |X1|
2x + y = 4 |X3|
———————-
6x - 8y = 1
6x + 3y = 12
—————— -
-11y = -11
y = 1
2). Mencari x
6x - 8y = 1 |X-1|
2x + y = 4 |X8|
————————
-6x + 8y = -1
16x + 8y = 32
——————— -
-22x = -33
2x = 3
x = 3/2
Pembuktian di salah satu persamaan
= 2(3/2) + 1
= 3 + 1
= 4
