\(3x-\dfrac{1}{2}=x+\dfrac{1}{2}\)
\(\Rightarrow3x-x=\dfrac{1}{2}+\dfrac{1}{2}\)
\(\Rightarrow2x=1\)
\(\Rightarrow x=\dfrac{1}{2}\)
\(4-\dfrac{7}{2}x-1=5\)
\(\Rightarrow3-\dfrac{7}{2}x=5\)
\(\Rightarrow\dfrac{7}{2}x=-2\)
\(\Rightarrow x=\dfrac{7}{2}:-2\)
\(\Rightarrow x=-\dfrac{7}{4}\)
`3x -1/2 =x+1/2`
`=> 3x-x=1/2+1/2`
`=> 2x= 2/4 + 2/4`
`=> 2x= 1`
`=>x=1/2`

`4- 7/2 x -1=5`
`=> 4- 7/2x -1-5=0`
`=> -7/2x-2=0`
`=> -7/2x=2`
`=>x=2:(-7/2)`
`=>x= -7/4`
