Quiz (11/20)

Jawaban:

500² – 50² – x = 4x

(500 – 50) × (500 + 50) – x = 4x

450 × 550 – x = 4x

247.500 – x = 4x

– x = 4x – 247.500

– x – 4x = 247.500

– 5x = – 247.500

x = – 247.500 ÷ (-5)

x = 247.500 ÷ 5

x = 49.500

#maaf kalau salah

→ 500² – 50² – x = 4x

→ 250.000 – 2.500 = 4x + x

→ 247.500 = 5x

→ 5x = 247.500

→ x = 49.500
