\(\dfrac{x}{3}-\dfrac{1}{2}=\dfrac{1}{5}\)

\(\dfrac{x}{3}=\dfrac{1}{5}+\dfrac{1}{2}\)

\(\dfrac{x}{3}=\dfrac{7}{10}\)

\(10x=21\)

\(x=2,1\)

\(\dfrac{x}{3}-\dfrac{1}{2}=\dfrac{1}{5}\)

\(\dfrac{x}{3}=\dfrac{1}{5}+\dfrac{1}{2}\)

\(\dfrac{x}{3}=\dfrac{7}{10}\)

\(x=\dfrac{\left(7\cdot3\right)}{10}\)

\(x=\dfrac{21}{10}\)

|-2|=2x+3

<=> 2x+3=|-2|

=>2x+3=2

=>2x=2-3

=>2x=-1

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

/ -2 / = 2x + 3

\(=>2=2x+3\)

\(=>-1=2x\)

\(=>-2x=1\)

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

Ủng hộ mik nha

                   2x + 3 = |-2|

                   2x + 3 = 2

                    2x = 2 + 3

                    2x = 5

                       x = 5/2

                  ủng hộ mk nha!!!

-12.(x-5)+7.(3-x)=5

-12x-60+21-7x=5

(-12x-7x)-(60+21)=5

-19x-81=5

-19x=5-81

-19x=-76

x=-76:(-19)

x=4

x=

x=44:(-19)

\(-12\left(x-5\right)+7\left(3-x\right)=5\)

\(60-12x+21-7x=5\)

\(81-19x=5\)

\(19x=81-5\)

\(19x=76\)

\(x=4\)

bn trí sai ròi ender ms đúng đó

Pleaseeeeeee!

Câu hỏi nó hơn cụt ý nha em
