Question

X − 270 ∶ 3 ∶ 3 + × 3 = 1250

Answer 1

X - 270 : 3 : 3 x 3 = 1250

X - 90 = 1250

X = 1250 + 90

X = 1340

Vậy X = 1340

Answer 2

Ta có: \(x-270:3:3\cdot3=1250\)

\(\Leftrightarrow x-30\cdot3=1250\)

hay x=1340

Vậy: x=1340

Answer 3

\(x-270:3:3.3=1250\) 

              \(x-90=1250\) 

                      \(x=1250+90\) 

                      \(x=1340\)
