Question

(4,5-2.x).11/7=11/14

Answer 1

\(\left(4,5-2x\right)\cdot\dfrac{11}{7}=\dfrac{11}{14}\)

=>\(4,5-2x=\dfrac{11}{14}:\dfrac{11}{7}=\dfrac{7}{14}=0,5\)

=>2x=4,5-0,5=4

=>\(x=\dfrac{4}{2}=2\)

Answer 2

$#flo$

`(4,5 - 2x ) . 11/7 = 11/14`

`=> 4,5 - 2x = 11/14 : 11/7`

`=>4,5 - 2x = 1/2`

`=>         2x = 4,5 - 0,5`

`=>         2x = 4`

`=>           x = 2`

 

Answer 3

( 4,5 -2.x).11/7=11/14

4,5-2.x= 11/14:11/7

4,5-2.x=11/14.7/11

4,5-2.x=1/2=0.5

      2.x=4,5-0,5

       2.x=4

          x= 4 : 2 = 2
