Harga 2 kg mangga, 2 kg jeruk, dan 1 kg anggur adalah Rp 70.000,00. Harga 1 kg mangga, 2 kg jeruk dan 2 kg anggur adalah Rp 90.000,00. harga 2 kg mangga, 2 kg jeruk dan 3 kg anggur Rp 130.000,00. Maka persamaan linearnya adalah...
x + y + z = 70.000
x + 2y + 2z = 90.000
2x + 2y + 3z = 130.000
2x + 2y + z = 70.000
x + y + 2z = 90.000
x + y + 3z = 130.000
2x + 2y + z = 70.000
x + 2y + 2z = 90.000
2x + 2y + 3z = 130.000
2x + z = 70.000
x + 2y + 2z = 90.000
x + 2y + z = 130.000
