Question

x - 1/2 = 3/4. 1/6 - x = 1/7

Answer 1

`x-1/2 =3/4`

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

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

`=>x= 5/4`

`----`

`1/6-x=1/7`

`=>x=1/6-1/7`

`=>x= 7/42 - 6/42`

`=>x=1/42`

Answer 2

\(x-\dfrac{1}{12}=\dfrac{3}{4}\\ x-\dfrac{1}{12}=\dfrac{9}{12}\\ x=\dfrac{9}{12}+\dfrac{1}{12}\\ x=\dfrac{5}{6}\\ \\ \dfrac{1}{6}-x=\dfrac{1}{7}\\ x=\dfrac{1}{6}-\dfrac{1}{7}\\ x=\dfrac{7}{42}-\dfrac{6}{42}\\ x=\dfrac{1}{42}\)
