Verified answer
Kurma = xkismis = y
diketahui :
3x+2y = 220.000
5x=4y
x =
substitusi nilai x ke persamaan pertama
3x+2y = 220.000
3() + 2y = 220000
y = 220000
y = 10000 (5)
y=5000
substitusi nilai y
x =
x = 40000
maka 2x + 5y = 330000

Misal :harga kurma = a
harga kismis = b
maka :
3a + 2b = Rp 220.000,00
5a = 4b
5a = 4b
a = 4b/5
3a + 2b = 220.000
3(4b/5) + 2b = 220.000
12b/5 + 10b/5 = 220.000
22b/5 = 220.000
b = 220.000 × 5/22
b = Rp 50.000,00
a = 4b/5
a = 4(50.000)/5
a = 200.000/5
a = Rp 40.000,00
2a + 5b
= 2(40.000) + 5(50.000)
= 80.000 + 250.000
= Rp 330.000,00
