a) x - 4867 = 2050.70. (175: 25) + 23

x - 4867 = 2050.70.7 + 23 =  1004 500 => x = 1 004 500 + 4867 =  1 009 367

b)  => (697 / 15) : x + 364 : x = 17 =>  \(\left(\frac{697}{15}+364\right):x=17\)

=> \(\frac{6157}{15}:x=17\) => x = \(\frac{6157}{15}:17=\frac{6157}{255}\)

c) => \(341=\frac{x+350}{x+315}\) => 341.(x+315) = x + 350 => 341x + 341.315 = x + 350 

=> 341x - x = 350 - 341.315 => 340x = -107 065 => x = -107 065 : 340 =....

mik chỉ biết làm phần b thôi thông cảm

đáp án phần B là 17

Good luck !

\(697:\frac{15x+364}{x}=17\)

          \(\frac{15x+364}{x}=697:17=41\)

           \(\frac{15x}{x}+\frac{364}{x}=41\)

            \(15+\frac{364}{x}=41\)

                        \(\frac{364}{x}=41-15=26\)

                         \(x=364:26=14\)

\(92.4-27=\frac{x+350}{x}+315\)

      \(\frac{x+350}{x}+315=341\)

                   \(\frac{x+350}{x}=341-315=26\)

                \(\frac{x}{x}+\frac{350}{x}=26\)

                     \(1+\frac{350}{x}=26\)

                              \(\frac{350}{x}=26-1=25\)

                                   \(x=350:25=14\)

a) \(697:\frac{15X+364}{X}=17\)

\(\Rightarrow\frac{15X+364}{X}=697:17=41\)

\(\Rightarrow15X+364=41X\)

\(\Rightarrow364=41X-15X=26X\)

\(\Rightarrow X=14\)

THANKYOU.

A.suy ra: 15x+364/x=41

  suy ra: 15x/x+364/x=41

  suy ra: 15 + 364/x=41

  suy ra: 364/x        =26

  suy ra: 364:x=26

  suy ra: x= 14 (T/M)

B. 92.4-27=x+350/x+315

  suy ra: 341=x/x+ 350/x +315

  suy ra: 26 =1+350/x

  suy ra: 25=350/x

  suy ra: 350:25=x

  suy ra: 14=x (T/M)

Vậy a. x=14

       b. x=14
