Question

3x - 1/2 = x +1/2

4 - 7/2x - 1 = 5

Answer 1

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

\(\Rightarrow3x-x=\dfrac{1}{2}+\dfrac{1}{2}\)

\(\Rightarrow2x=1\)

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

\(4-\dfrac{7}{2}x-1=5\)

\(\Rightarrow3-\dfrac{7}{2}x=5\)

\(\Rightarrow\dfrac{7}{2}x=-2\)

\(\Rightarrow x=\dfrac{7}{2}:-2\)

\(\Rightarrow x=-\dfrac{7}{4}\)

Answer 2

`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`
