Question

tìm x

-45: 5. ( -3-2.x)=3

Answer 1

-45 : 5 (-3-2x)=3

<=> -9(-3-2x)=3

<=>-3-2x=-1/3

<=> 2x = -8/3

<=> x = -4/3

Vậy ...

Answer 2

-45 : 5 . ( -3 - 2 . x ) = 3

<=> -9 . ( -3 - 2 . x ) = 3

<=> -3 - 2 . x = 3 : ( - 9 )

<=> -3 - 2 . x = -1/3

<=> 2x = -3 - ( -1/3 )

<=> 2x = -8/3

<=> x = -4/3

Answer 3

\(\text{-45: 5. ( -3-2.x)=3}\)

\(< =>9. ( -3-2.x)=3\)

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

\(< =>2x=-\frac{8}{3}\)

\(< =>x=-\frac{4}{3}\)

Vậy x=\(-\frac{4}{3}\)

chúc bạn học tốt !

Answer 4

- 45 : 5 ( - 3 - 2x) = 3

<=> -9( -3 - 2x) = 3

<=> 27 + 18x = 3

<=> 18x = 3 - 27

<=> 18x = -24

<=> x =\(\frac{-4}{3}\)

Vậy_

Answer 5

\(-45:5\left(-3-2x\right)=3\)

\(\Rightarrow-9\left(-3-2x\right)=3\)

\(\Rightarrow27+18x=3\)

\(\Rightarrow18x=3-27=-24\)

\(\Rightarrow x=\frac{-4}{3}\)
