4b + 3p = 11.750
5b = 8p
Penyelesaian
∴ 5b = 8p
b =8p/5
∴ 4b+3p = 11.750
4(8p/5) + 3p = 11.750
32p/5 + 3p = 11.750
32p/5 + 15p/5=11.750
47p/5 = 11.750
47p = 11.750 × 5
47p = 58.750
p = 1.250
Harga satu pensil adalah Rp1.250,00
5x = 8y
x = 8/5 y
disubstitusikan ke :
4x+3y = 11.750
4(8/5 y) + 3y = 11.750
32/5 y + 3y = 11.750
32/5 y + 15/5 y = 11.750
47/5 y = 11.750
y = 11.750 : 47/5
y = 11.750 x 5/47
y = 1.250
jadi, harga 1 pensil adalah Rp 1.250,00
