hk tốt

     92 . 4 - 27 = (x+ 350 ) : x + 315

<=> 365 -  27 = (x + 350):x +315

<=> 341         = (x+350 : x +315

<=> (x + 350 ): x = 341 - 315

<=> (x + 350 ) : x = 26 

<=>(x + 350 ) . 1/x=26

<=> x . 1/x + 350 . 1/x = 26

<=> 1 + 350/x =26

<=> 350/x       = 26-1

<=> 350 : x      = 25

<=> x               = 350 : 25 

<=> x                = 14

   vậy x = 14

tít cho mình trước nha

92 × 4 -27 = ( x + 350 ) : x + 315

hay \(\left(x+350\right):x+315=92\) x \(4-27\)

\(\left(x+350\right):x=368-27-315\)

\(\left(x+350\right):x=26\)

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

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

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

\(\frac{350}{x}=25\)

\(x=350:25\)

\(x=14\)

a) \(92.4-27=\frac{x+350}{x}+315\)

\(368-27=1+\frac{350}{x}+315\)

\(341=\frac{350}{x}+316\)

\(341-316=\frac{350}{x}\)

\(25=\frac{350}{x}\)

\(25x=350\)

\(x=14\)

b) \(\left(\frac{3}{2}-x\right).\frac{1}{3}-\frac{2}{3}.\left(\frac{1}{2}-x\right)=\frac{1}{3}\)

\(\frac{\frac{3}{2}}{3}-\frac{x}{3}-\frac{2}{3}.\left(\frac{1}{2}-x\right)=\frac{1}{3}\)

\(\frac{1}{2}-\frac{x}{2}-\frac{2}{3}.\left(\frac{1}{2}-x\right)=\frac{1}{3}\)

\(\frac{3}{2}-x-2.\left(\frac{1}{2}-x\right)=1\)

\(\frac{3}{2}-x-1+2x=1\)

\(\frac{1}{2}+x=1\)

\(x=1-\frac{1}{2}\)

\(x=\frac{1}{2}\)

[(x + 32) - 17] . 2 = 42

(x + 32) - 17 = 42 : 2

(x + 32) - 17 = 21

x + 32 = 21 + 17 

x + 32 = 38

x = 38 - 32

x = 6

Vậy x = 6

a) [ (x + 32 ) - 17 ] * 2 = 42

[ (x + 32 ) - 17 ] = 42 : 2

 (x + 32 ) - 17  = 21

 (x + 32 )  = 21 + 17 

 x + 32     = 38

x = 38 - 32

x = 6
