Misalkan uang Budi = b.
a + 3b = 32.500
a = 32.500 - 3b
2a + 4b = 50.000
2(32.500 - 3b) + 4b = 50.000
65.000 - 6b + 4b = 50.000
-6b + 4b = 50.000 - 65.000
-2b = -15.000
b = 7.500
a + 3b = 32.500
a + 3(7.500) = 32.500
a + 22.500 = 32.500
a = 32.500 - 22.500
a = 10.000
Jadi uang Andri adalah Rp 10.000,00. Sedangkan uang Budi adalah Rp 7.500,00.
