• no is 105-x, then
  
  (105-x)*13 = 105+x
  1365 -13 x =105+x
  14x = 1260
  x= 1260/14 =90

• Let no is x.
  13*x = 105 + (105-x)
  13x = 105+105-x
  13x= 210 -x
  14x = 210
  x = 15

• Let the number be x.
  Let y is amount with which x is lesser to 105 by now.
  y=105-x
  
  13x = 105 + y ..... (statement given)
  13x = 105 + (105-x)
  13x = 105 + 105 - x
  13x+x = 210
  14x = 210
  x = 210/14
  x = 15
