Question

The sum of the number and three times its reciprocal is 79/10. Find the number.

Answer 1

hi  

so    x + 3 (-x)  =  79/10

        x-3x = 79/10

         -2x = 79/10

             x =   79/10 / -2  

              X =   79/ 10 *   -1/2

              x =     - 79/20

              x =   - 3.95
