Anak : y
(x-2) = 8.(y-2)
x-2 = 8y - 16
x-8y = -14 persamaan pertama
(x+4) = 19/5 (y+4)
x+4 = 19/5 y + 76/5
5x + 20 = 19y + 76
5x- 19y = 56 persamaan kedua
eliminasi x
x - 8y = -14 ( x 5) 5x-40y = -70
5x - 19y = 56 ( x1 ) 5x - 19y = 56 _
-21y = -126
y = 6
Substitusi y ke persamaan pertama
x- 48 = -14
x = 48-14
x = 34
Maaf kalau salah
