Verified answer
3x + y = -7 |×32x - 3y = 10 |×1
___________
9x + 3y = - 21
2x - 3y = 10
___________ +
11x = - 11
x = - 1
Substitusi
3x + y = - 7
3(-1) + y = - 7
-3 + y = - 7
y = - 7 + 3
y = - 4
Hp = {-1,-4}
2x-3y=10(ditambah)
Eliminasi y
9x+3y=-21
2x-3y=10(di tambah)
11x. =-11
X. =-11/11
X. =-1
Masukan ke persamaan satu(1)
3x+y=-7
3(-1)+y=-7
-3+y=-7
Y. =-7+3
Y. =-4
HP{-1,-4}
