Soal cerita tentang sistem persamaan KLS 10 Sinta mmbeli 2 kg salak, 1 kg jeruk , dan 2 kg apel degan harga Rp68.000,00 Sari mmbeli 2 kg salak , 2kg jeruk dan 1

salak= x jeruk=y apel = z
2x+y+2z=68.000
2x+2y+z=60.000
2x+3y+2z= 92.000
●2x+y+2z=68.000
2x+2y+z=60.000 dikurangi
-2y+z==8000
●2x+y+2z=68000
2x+3y+2z=92000 dikurangi
-2y=-24000
y=-24000/-2
y=12.000
●-2y+z=8000
-2x 12000+z=8000
z=8000+24.000
z=32.000
●2x+2y+z=68000
2x+12000x2+32000=68000
2x= 68.000-56000
x=12000/2
x=6000
1 kg jeruk(y)=12.000
1kg apel(z)=32000
1 kgsalak(x)=6000

Harga 1 kg jeruk = Rp 12.000
Harga 1 kg apel = Rp 20.000
Harga 1 kg salak = Rp 8.000
