Câu 7: Tìm x

b) 259 + x = 428 – 92

Answer 1

b) 259 + x = 428 – 92
259 + x= 336
x= 336 - 259
x= 77

Answer 2

\(x=\left(428-92\right)-259\Rightarrow x=77\)

Answer 3

259 + x = 336

x = 336 - 259

x = 77

Answer 4

259 + x = 428 - 92

259 + x = 336

x= 336 - 259 

x= 77

Answer 5

259 + x = 428 - 92 

259 + x = 336 

x =  336 - 259 = 77

vậy x = 77
