Quyidagi berilgan tenglamalarning qaysi birining yechimi yo'q?

2 × (−x + 1) − 4 = −2x + 5
x − 1 = −2
9x − 1 = 7x
2 × (x + 1) = 3 × (x + 5)

📝 Batafsil tushuntirish

Birinchi tenglamani soddalashtiramiz: −2x + 2 − 4 = −2x + 5 ⇒ −2x − 2 = −2x + 5 ⇒ −2 = 5. Bu noto'g'ri tenglik bo'lgani uchun tenglama yechimga ega emas.
