nxyaptrf

Penjelasan dengan langkah-langkah:

= 10.10 + 7.10 - 20

= 100 + 70 - 20

= 170 - 20

= 150

= 20.5 - 15.5 × 26²

= 100 - 75 × 676

= 100 - 50.700

= - 50.600

• Nomor 1 :

$\tt10y + 7y - 20$

$\tt{y = 10}$

-----------------------------------------------------

= 10(10) + 7(10) - 20

= (10 × 10) + (7 × 10) - 20

= 100 + 70 - 20

= 170 - 20

= 150 ✔

___________________

• Nomor 2 :

$\tt20x - 15x \times {26}^{2}$

$\tt{x = 5}$

------------------------------------------------------

= 20(5) - 15(5) × 26²

= (20 × 5) - (15 × 5) × (26 × 26)

= 100 - 75 × 676

= 100 - 50.700

= -50.600 ✔
