Question

X − 270 ∶ 3 ∶ 3 + X × 3 = 1250

Answer 1

Ta có : \(3x=1250+\dfrac{270}{\dfrac{3}{3}}=1250+\dfrac{270}{9}=1250+30=1280\)

\(\Rightarrow x=\dfrac{1280}{3}\)

Vậy ...

Answer 2

$-270 :3:3 + x .3 = 1250$

$\to -30 + 3x = 1250$

$\to 3x = 1280$

$\to x = \dfrac{1280}{3}$

Vậy : $ x = \dfrac{1280}{3}$

 

Answer 3

- 270 : 3 : 3 + X x 3 = 1250

- 270 : 9 + X x 3 = 1250

- 30 + X x 3 = 1250

X x 3 = 1280

X = \(\dfrac{1280}{3}\)

Answer 4

Ta có: \(x-270:3:3+x\cdot3=1250\)

\(\Leftrightarrow4x-30=1250\)

\(\Leftrightarrow4x=1280\)

hay x=320

Vậy: x=320

Answer 5

\(x-\dfrac{270}{3}:3+3x=1250\\ \Leftrightarrow x-30+3x=1250\\ \Leftrightarrow-2x=1280\\ \Rightarrow x=-640\)

Answer 6

\(x-270:3:3+x.3=1250\) 

        \(x.\left(1+3\right)-30=1250\) 

                          \(x.4=1250+30\) 

                          \(x.4=1280\) 

                             \(x=1280:4\) 

                             \(x=320\)
