2x – 3y = 7 4x + 2y = 22

2x – 3y = 7|× 2
4x + 2y = 22|× 3

4x – 6y = 14
12x + 6y = 66
__________+
16x = 80
x = 5

2x – 3y = 7
10 – 3y = 7
– 3y = 7 – 10
– 3y = – 3
y = 1

Maaf Kalau Salah

2x – 3 y = 7 —(dikali 4)
4x + 2y = 22 –(dikali 2)
menjadi
8x – 12y = 28
8x + 4y = 44
——————— dikurangi
-16y = -16
y = 1

subtitusi pada persamaan 1
2x – 3y =7
2x – 3.1 = 7
2x-3 =7
2x = 7 + 3
2x = 10
x = 10/2
x = 5
