Question

108:(30-x)=90

 

Answer 1

108:( 30-x )=90

      30-x    =108:90

      30-x    =1,2

           x    = 30-1,2

           x    =28,8

Answer 2

108 : ( 30 - x ) = 90

       30 - x      = 108 : 90

        30 - x     = 1,2

              x     = 30 - 1,2

             x      = 28,8

Answer 3

108 : (30 - x) = 90

30 - x = 108 : 90

30 - x = 1,2

x = 30 - 1,2

x = 28,8

Vậy x = 28,8

Answer 4

108 : (30 - x) = 90

         30 - x  = 108 : 90

         30 - x  = \(\frac{6}{5}\)

               x   = 30 - \(\frac{6}{5}\)

               x   = \(\frac{144}{5}\)

Answer 5

180 : (30-x) = 90 

=> 30 -x = 180 : 90 

=> 30 -x = 2 

=> x = 30 - 2 = 28

=> x = 28

Answer 6

X = 30 - (108:90)

X = 28,8

Answer 7

108:(30-x)=90

=>30-x=108:90

=>30-x=\(\frac{6}{5}\)

=>x=30-

Answer 8

108:(30-x)=90

30-x=108:90

30-x=1,2

x=30-1,2

x=28,8 hoac =144/5

Answer 9

180 : (30-x) = 90 

=> 30 -x = 180 : 90 

=> 30 -x = 2 

=> x = 30 - 2 = 28

=> x = 28
