Penjelasan dengan langkah-langkah:
- Bagian 1
50x + 34 - 34 = 700
50x = 700 - 34 + 34
50x = 666 + 34
50x = 700
x = 700/50
x = 14

- Bagian 3
Jika:
('50) = (100 ÷ 2) + 20 - (4 × 1)
= 50 + 20 - 4
= 70 - 4
= 66
("50) = (50 ÷ 2) - 4 + (4 × 2)
= 25 - 4 + 8
= 21 + 8
= 29
("'50) = ((100 ÷ 10) × 2) + 8 - 3
= (10 × 2) + 8 - 3
= 20 + 8 - 3
= 28 - 3
= 25
Maka:
('50) + ("50) - ("'50) = ?
Jawab:
('50) + ("50) - ("'50)
= 66 + 29 - 25
= 95 - 25
= 70
