2a+6m=46.000 =>2X 4a+12m=92.000
4a+3m=47.000 =>1X 4a+3m = 47.000
-------------------------- --
9m=45.000 => m=5000 -> 1 kg melon 5 ribu. berarti apel=> 2a+30000=46000=> 1kgapel=8000
5x8000+3x5000=40000+15000=55000
x=apel
y=melon
2x + 6y= 46000 ·2 ⇔ 4x + 12y= 92000
4x + 3y= 47000 ·1 ⇔ 4x + 3y= 47000
= 9y= 45000
y= 5000
4x + 3y= 47000 ⇒ 4x + 3(5000)= 47000
=4x + 15000 = 47000
= 4x= 32000
x= 8000
5x + 3y= 5(8000) + 3(5000)
= 40000+15000
= 55000
