5x + 3y = 60.500
= 6x + 15y =141.000
25x + 15y =302.500
-------------------------------------- -
19y = 161.500
y = 8.500
2x + 5y = 47.000
2x + 5 . 8500 = 47.000
2x+ 42.500 = 47.000
2x= 47.000 - 42.500
2x = 4.500
x= 2.250
maka x + 2y = 2.250 + 2 . 8500
=2.250 + 17.000
= 19.250
5x+3y=60500
dit : x+2y=?
jwb :
2x+5y=47000 -->x5 -->10x+25y=235000
5x+3y=60500 -->x2 -->10x+ 6y=121000
_________________________________ -
19y=114000
y=114000/19
y=6000
2x+5y=47000
2x+5(6000)=47000
2x+30000=47000
2x=47000-30000
2x=17000
x=8500
jadi 1kg apel dan 2kg jeruk = (1).8500 + (2).6000 =8500+12000 = 20500
SEMOGA TERBANTU ^_^
