Question

tìm X:

( X - 2,5) x 1,2 = 6,216

ai nhanh mình tick

Answer 1

(x- 2,5 ) x 1,2 = 6,216

(x - 2,5 )        = 6,216 / 1,2

x- 2,5            = 5,18

x                   = 5,18 + 2,5

x                   = 7,68

Vậy x = .....

Answer 2

\(\left(x-2,5\right)\times1,2=6,216\)

\(\Leftrightarrow x-2,5=6,216\div1,2\)

\(\Leftrightarrow x-2,5=5,18\)

\(\Leftrightarrow x=5,18+2,5\)

\(\Leftrightarrow x=7,68\)

\(\text{Vậy }x=7,68\)

Answer 3

x-2,5=6,216/1,2

x= 6,216/1,2+2,5

x=7,68

Answer 4

⇔x−2,5=6,216÷1,2

⇔x−2,5=5,18

⇔x=5,18+2,5

⇔x=7,68
