2y-4x = 2
Eliminasi (dikurang)-->
6x= -6
x= -1
Substitusi x= -1
2y-4x=2
2y-4(-1)=2
2y+4=2
2y= -2
y = -1
b) 4x-6y = -26
2x+4y = 4 <=> (*2) --> 4x+8y=8
Eliminasi (dikurang)-->
-14y= -34
y=34/14
substitusi y= 2
2x+4y=4
2x+4(34/14)=4
2x+13,6 = 4
2x= -9,6
x= - 4,8
c) 2x= -y+6 <=> y=6-2x
4x+2y= 8
Substitusi y=6-2x
4x+2(6-2x)=8
4x+12-4x=8
(maaf sampai disini saya tdk bisa melanjutkan lagi)
