x-y=-86 (dieliminasi)
2x=-64
x=-32
x+y=22(disubstitusi)
y=22+32=54
jadi bilangan terkecilnya yaitu -32
x - y = -86
maka: persamaan (1)
x + y = 22, x = 22 - y
disubtitusikan ke x - y = -86
menjadi (22 - y) - y = -86
22 - 2 y = -86
22 + 86 = 2y
108 = 2 y
y = 54
sehingga x + y = 22
x + 54 = 22
x = 22 - 54
x = -32
