Jadi,eliminasi pers (1) dan (2)
5x+4y=84.000... (1) | ×2| 10x+8y=168.000
2x+3y=42.000... (2) | ×5| 10x+15y=210.000
----------------------------- - ----------------------------- -
3y= -42.000
y= -14.000
Substitusikan y=-14.000 ke pers 1
5x+4y=84.000
5x +4 (-14.000) =84.000
5x-56.000=84.000
5x=84.000+56.000
x=140.000/5
x=28.000
Jadi 2kg jeruk
2x
=2 (28.000)
=56.000
