\(x\times98+x:0,5=2017\)

\(x\times98+x\times2=2017\)

   \(x\times\left(98+2\right)=2017\)

             \(x\times100=2017\)

                          \(x=2017:100\)

                          \(x=20,17\)

\(x\times98+x\div0,5=2017\)

\(x\times98+x\times2=2017\)

\(x\times\left(98+2\right)=2017\)

\(x\times100=2017\)

\(x=2017\div100\)

\(x=20,17\)

x x 98 + x : 0,5 = 2017

x x 98 + x x 2 = 2017

x x ( 98 + 2 ) = 2017

x x 100 = 2017

x = 2017 : 100

x = 2017

52000 tick minh nha help me plaseeeeeeeeeee.......!!!!

A=[(38+17)+125]+29

A=175+29

A=204

B=312.3

B=936

C=1+1+1+1+1

C=5

D=(125:5).(36:9)

D=25.4

D=100

x:125+98=275

x:125=275-98

x:125=177

x=177x125

x=22125

Vậy x=22125.

TL:

x : 125 + 98 = 275

x: 125 = 275 - 98

x: 125 = 177

x = 177 x 125

x = 22125

Hok tốt 

#Devil 2k6

\(x\div125+98=275\)

\(x\div125=275-98\)

\(x\div125=177\)

               \(x=177\times125\)

               \(x=22125\)

x = 5

k nha ^_^

125-3(x+4)=98

      3(x+4)=125-98

      3(x+4)=27

        (x+4)=27:3

        (x+4)=9

            x=9-4

            x=5

=125.(98-46)-52.25

=125.52-52.25

=(125-25).52

=100.52

=5200

chú ý . là nhân

( x + 1 ) + ( x + 2 ) + ... + ( x + 98 ) + ( x + 99 ) = 9900

( x + x + ... + x + x ) + ( 1 + 2 + ... + 98 + 99 ) = 9900

99.x + \(\frac{\left(99+1\right).99}{2}\)= 9900

99.x + 4950 = 9900

99.x = 9900 - 4950

99.x = 4950

x = 4950 : 99

x = 50

2 . x + 5 . x - 3 . x = 125 : 4 + 27 : 3

x . ( 2 + 5 - 3 ) = 31,25 + 9

x . 4 = 40,25

x = 40,25 : 4

x = 10,0625

phan thuhai???
