misalkan jeruk = x dan pisang = y
3x + 4y = 26500 X 5 = 15x + 20y = 132.500
5x + 3y = 29500 X 3 = 15x + 9y = 88500
________________________________________-
11y = 44.000
y = 4.000
5x + 3*4000 = 29.500
5x + 12 .000 = 29.500
5x = 29.500-12.000
x = 17.500 : 5
x = 3500
2jeruk + 1 pisang
2x + y = 2*3.500 + 4.000
7.000 + 4.000 = 11.000
