`6/5 - x : 1/2 = 1/2`
`=> x : 1/2 =6/5 - 1/2`
`=> x : 1/2 = 7/10`
`=> x= 7/10 xx 1/2`
`=>x= 7/20`
\(\dfrac{6}{5}-x:\dfrac{1}{2}=\dfrac{1}{2}\)
\(x:\dfrac{1}{2}=\dfrac{6}{5}-\dfrac{1}{2}\)
\(x:\dfrac{1}{2}=\dfrac{12}{10}-\dfrac{5}{10}\)
\(x:\dfrac{1}{2}=\dfrac{7}{10}\)
\(x=\dfrac{7}{10}.\dfrac{1}{2}\)
\(\Rightarrow x=\dfrac{7}{20}\)
65−x:12=1265-x:12=12
⇒ x:12=65−12⇒ x:12=65-12
⇒ x:12=710⇒ x:12=710
⇒x=710×12⇒x=710×12
⇒x=720
