Question

154-X:1,2=23,6x45

Answer 1

Ta có : \(154-\dfrac{x}{1,2}=23,6.45=1062\)

\(\Leftrightarrow\dfrac{x}{1,2}=154-1062=-908\)

\(\Leftrightarrow x=-1089,6\)

Vậy ...

Answer 2

Ta có: \(154-x:1.2=23.6\cdot45\)

\(\Leftrightarrow154-2x=1062\)

\(\Leftrightarrow2x=-908\)

hay x=-454

Vậy: x=-454

Answer 3

154 - X : 1,2 = 23,6 x 45

154 - X : 1,2 = 1062

X : 1,2 = - 908

X = - 1089,6

Vậy X = - 1089,6
