Question

1.TÌM X,

A. 697:\(\frac{15.X+364}{X}\)=17

B. 92.4-27=\(\frac{X+350}{X}\)+315

 

Answer 1

a) \(697:\frac{15X+364}{X}=17\)

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

\(\Rightarrow15X+364=41X\)

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

\(\Rightarrow X=14\)

Answer 2

THANKYOU.

Answer 3

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

Answer 4

số đó là

x=14

nhé bn

mình làm

đúng ko vậy

Answer 5

\(a,\text{ }697\text{ : }\frac{15\cdot x+364}{x}=17\)

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

       \(\frac{15\cdot x+364}{x}=41\)

      \(15x+364=41x\)

       \(41x-15x=364\)

        \(26x=364\)

             \(x=364\text{ : }26\)

            \(x=14\)

Answer 6

A. \(697:\frac{15.X+364}{X}=17\)

\(\Leftrightarrow15+\frac{364}{X}=697:17=41\)

\(\Leftrightarrow\frac{364}{X}=41-15=26\Leftrightarrow X=364:26=14\)

B. \(92.4-27=\frac{X+350}{X}+315\)

\(\Leftrightarrow368-27=341=1+\frac{350}{X}+315\)

\(\Leftrightarrow341-315=26=1+\frac{350}{X}\)

\(\Leftrightarrow\frac{350}{X}=26-1=25\Leftrightarrow X=350:25=14.\)
