1/3 x - 2y = -7 kalikan 6 juga akan menjadi 2x - 12y = -42
------------------------------------------------------------------------------------- -
15y = 60
y= 60/15
y = 4
susikan 2x+3y=18
2x+3(4)=18
2x + 12 = 18
2x= 18 -12
2x = 6
x=-6/2
x= 3
sehingga hasilnya akan menjadi
2x+3y=18
2x-12y=-42
---------------- -
15y=60
y=4
susikan 2x+12=18
x=3
