10x + 11y × 2x - 22y
x → 10
y → 5
___________________________________________ 10(10) + 11(5) × 2(10) - 22(5)
= 100 + 54 × 20 - 110
= 100 + 1.080 - 110
= 100 + 970
= 1.070
Penjelasan dengan langkah-langkah:
x = 10
y = 5
= 10(10) + 11(5) × 2(10) - 22(5)
= (10 × 10) + (11 × 5) × (2 × 10) - (22 × 5)
= 100 + (55 × 20) - 110
= 100 + 1.100 - 110
= 1.200 - 110
= 1.090
