Question

(3x+2)-(x-1)=4*(x+1) giúp ạ

Answer 1

`(3x+2)-(x-1)=4(x+1)`

`=>3x+2-x+1=4x+4`

`=>2x+3=4x+4`

`=>4x-2x=3-4`

`=>2x=-1`

`=>x=-1/2`

Answer 2

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

Answer 3

X=\(\dfrac{7}{2}\)

Answer 4

\(\left(3x+2\right)-\left(x-1\right)=4\left(x+1\right)\)

\(\Rightarrow3x+2-x+1=4x+4\)

\(\Rightarrow2x+3=4x+4\)

\(\Rightarrow4x-2x=3-4\)

\(\Rightarrow2x=-1\)

\(\Rightarrow x=-\dfrac{1}{2}\)

Vậy \(x=-\dfrac{1}{2}\)
