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

khong can lam nua dau minh biet lam roi

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 !

a,697:[(15.x+364):x]=17

=>(15x+364):x=679:17=41

=>\(\frac{15x}{x}+\frac{364}{x}=41\) 

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

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

=>\(x=\frac{364}{26}=14\)

b,92.4-27=(x+350):x+317

=>\(341=\left(x+350\right):x+317\)

=>\(\left(x+350\right):x=341-317=24\)

=>\(\frac{x}{x}+\frac{350}{x}=24\)

=>\(1+\frac{350}{x}=24\)

=>\(\frac{350}{x}=23\) => \(x=350:23=\frac{350}{23}\)

em cảm ơn ạ

tịt???????????????????????????????????????___________________????????????????????????????????????????????????

\(\frac{15.a+364}{a}\)= 697:17=41

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

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

       a=364:26

        a=14

368-27=\(\frac{a+350}{a}\)+315

314=\(\frac{a+350}{a}\)+315

a+350=26.a

bài này ở đâu zay khó wa

x - 4867 = ( 175 . 2050 . 70 ) : 25 + 23

x - 4867 = ( 358750 . 70 ) : 25 + 23

x - 4867 = 25112500 + 23

x - 4867 = 1004500 + 23 

x- 4867 = 1004523

x = 1004523 + 4867

x = 1009390

\(x-4867=\left(175.2050.70\right)\)\(:25+23\)

\(x-4867=\left(358750.70\right):25+23\)

\(x-4867=25112500+23\)

\(x-4867=1004500+23\)

\(x-4867=1004523\)

\(x=2004523+4867\)

\(x=1009390.\)
