Question

(48-3.x):5=9

Answer 1

$(48-3.x):5=9$

$48-3.x=9.5$

$48-3.x=45$

$3.x=48-45$

$3.x=3$

$x=3:3$

$x=1$

Answer 2

( 48 - 3 .x ) : 5 = 9

⇒ 48 - 3 . x = 45

⇒ 3 . x = 3

⇒ x = 1

Vậy x = 1.

Answer 3

\(\left(48-3\cdot x\right):5=9\)

\(\Rightarrow48-3\cdot x=9\cdot5\)

\(\Rightarrow48-3\cdot x=45\)

\(\Rightarrow3\cdot x=48-45\)

\(\Rightarrow3\cdot x=3\)

\(\Rightarrow x=\dfrac{3}{3}=1\)

Answer 4

...48-3x=9.5

48-3x=45

3x=48-45

3x=3

x=3:3=1

Answer 5

     (48 - 3 . x ) : 5=9
⇔ 48 - 3 . x = 9 . 5
⇔ 48 - 3 . x = 45
⇔        3 . x = 48 - 45
⇔        3 . x = 3
⇔             x = 3 : 3
            x = 1

Answer 6

( 48 - 3 * x) : 5 = 9
( 48 - 3 * x) = 9 * 5
( 48 - 3 * x)= 45
3 * x = 48 - 45
3 * x = 3
x = 3 : 3 
x = 1

Answer 7

(48-3x):5=9

=>48-3x=9x5=45

=>3x=48-45=3

=>x=3:3=1

Vậy x=1

Answer 8

9.5=(48-3.x)

 45=(48-3).x

  45=45.x

   x=45:45

   x=1

đúng 100%

Answer 9

X= 1
