[Shune Chimte]

Tìm x biết : 

(x - 23) : 14 + 25 = 42 - 1²⁰⁰²

Answer 1

[Tuan]

(x - 23) : 14 + 25 = 42 - 1²⁰⁰²

(x - 23) : 14 + 25 = 42 - 1

(x - 23) : 14 + 25 = 41

(x - 23) : 14 = 41 - 25

(x - 23) : 14 = 16

 x - 23 = 16 . 14

 x - 23 = 264

x = 224 + 23

x = 247

Answer 2

[Nguyễn Thị Mỹ Duyên]

(x-23):14+25=42-1²⁰⁰²

^{(x-23):14+25=42-1}

(x-23):14+25=41

(x-23):14=41-25

(x-23):14=16

x-23=16.14

x-23=224

x=224+23

x=247

Vậy x=247
