\(697:\frac{15x+364}{x}=17\)
\(\frac{15x+364}{x}=697:17=41\)
\(\frac{15x}{x}+\frac{364}{x}=41\)
\(15+\frac{364}{x}=41\)
\(\frac{364}{x}=41-15=26\)
\(x=364:26=14\)
\(92.4-27=\frac{x+350}{x}+315\)
\(\frac{x+350}{x}+315=341\)
\(\frac{x+350}{x}=341-315=26\)
\(\frac{x}{x}+\frac{350}{x}=26\)
\(1+\frac{350}{x}=26\)
\(\frac{350}{x}=26-1=25\)
\(x=350:25=14\)
a) \(697:\frac{15X+364}{X}=17\)
\(\Rightarrow\frac{15X+364}{X}=697:17=41\)
\(\Rightarrow15X+364=41X\)
\(\Rightarrow364=41X-15X=26X\)
\(\Rightarrow X=14\)
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
=>\(341=\left(x+350\right):x+317\)
=>\(\left(x+350\right):x=341-317=24\)
=>\(\frac{x}{x}+\frac{350}{x}=24\)
=>\(1+\frac{350}{x}=24\)
=>\(\frac{350}{x}=23\) => \(x=350:23=\frac{350}{23}\)

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
