Question

x+1/10+x+1/10=x+1/21

Answer 1

\(x\) + \(\dfrac{1}{10}\) + \(x\) + \(\dfrac{1}{10}\) = \(x\) + \(\dfrac{1}{21}\)

\(x+x\) - \(x\)  =  \(\dfrac{1}{21}\) -  \(\dfrac{1}{10}\) - \(\dfrac{1}{10}\) 

         \(x\)    = \(\dfrac{1}{21}\)  - \(\dfrac{1}{5}\) 

          \(x\) = - \(\dfrac{16}{105}\)
