-2x-5y=-10 (*2)=> -4x-10y=-20 (jumlahkan kedua persamaan agar x menjadi 0)
-13y = -26
y = 2
masukan nilai y ke salah satu persamaan :
4x-3y=-6 => 4x-3*(2)=-6
4x=0
x=0
semoga bermanfaat
-2x - 5y = - 10 (X-2)
=> 4x - 3y = -6
4x + 10y = 20 (dikurangi)
=> 7y = 14
y = 14/7
y = 2
* 4x - 3y = -6
4x - 3(2) = -6
4x = -6 + 6
x = -4
jadi nilai x = -4 dan y = 2
