Bạn nên viết đề bằng công thức toán và ghi đầy đủ yêu cầu đề để mọi người hiểu đề của bạn hơn nhé.

giúp mik với

\(a,\dfrac{x-3}{4}+\dfrac{2x-1}{3}=-\dfrac{x}{6}\)

\(\Leftrightarrow\dfrac{3\left(x-3\right)+4\left(2x-1\right)+2x}{12}=0\)

\(\Leftrightarrow3x-9+8x-4+2x=0\)

\(\Leftrightarrow13x-13=0\)

\(\Leftrightarrow13x=13\)

\(\Leftrightarrow x=1\)

\(b,\left(x-3\right)\left(2x-1\right)=\left(2x-1\right)\left(2x+3\right)\)

\(\Leftrightarrow\left(x-3\right)\left(2x-1\right)-\left(2x-1\right)\left(2x+3\right)=0\)

\(\Leftrightarrow\left(2x-1\right)\left(x-3-2x-3\right)=0\)

\(\Leftrightarrow\left[{}\begin{matrix}2x-1=0\\-x-6=0\end{matrix}\right.\)

\(\Leftrightarrow\left[{}\begin{matrix}x=\dfrac{1}{2}\\x=-6\end{matrix}\right.\)

a, x-3/4+2x-1/3=-x/6

b,(x-3)(2x-1)=(2x-1)(2x+3)

c,6/x-1-4/x-3+8/x^2-4x+3=0

a: =>1/3:x=3/5-2/3=9/15-10/15=-1/15

=>x=-1/3:1/15=5

b: \(\Leftrightarrow x\cdot\dfrac{2}{3}-3=\dfrac{2}{5}\cdot\left(-10\right)=-4\)

=>x*2/3=-1

=>x=-3/2

c: =>2x+1=4 hoặc 2x+1=-4

=>x=3/2 hoặc x=-5/2

h: =>x-3=4

=>x=7

g: =>2x-1=3

=>2x=4

=>x=2

f: \(\Leftrightarrow x\cdot\left(\dfrac{3}{2}-\dfrac{7}{3}\right)=\dfrac{3}{2}-\dfrac{2}{3}\)

=>x*-5/6=5/6

=>x=-1

d: =>|2x-1|=3

=>2x-1=3 hoặc 2x-1=-3

=>x=-1 hoặc x=2

a/\(\dfrac{7}{2}-2x=5\dfrac{1}{3}:\dfrac{8}{3}\)
\(\dfrac{7}{2}-2x=\dfrac{16}{3}:\dfrac{8}{3}\)
\(\dfrac{7}{2}-2x=2\)
\(2x=\dfrac{7}{2}-2\)
\(2x=\dfrac{3}{2}\)
\(x=\dfrac{3}{2}:2\)
\(x=\dfrac{3}{4}\)
b/Đề là gì ạ?

Khó nhìn qá bn à
