Verified answer
A = B + 500A + B = 3500
B + 500 + B = 3500
2B + 500 = 3500
2B = 3500 - 500
2B = 3000
B = 3000/2
B = 1500
Didapat B = 1500, maka A = 1500 + 500 = 2000
a- b = 500
a+b = 3500
a=500+b
500+b+b =3500
2b = 3500-500
2b =3000
b =1500
a-b = 500
a =500+1500
= 2000
jadi a = Rp.2000 dan b = Rp 1500
seoga bantu yaaa
