Hi,
The perimeter of a triangle with 2 equal sides is 46 cm. 
If its base were lengthened by 4 cm and each leg were shortened by 7 cm, all 3 sides would be equal.
Let b and s represent the length of the base and each side respectively. 
Question states***
  b + 4 = s - 7    or  s = (b + 11)
  b + 2s = 46cm
  b + 2(b+11) = 46
     3b = 24
      b = 8
and..
CHECKING our Answer***  s = 19
  {{{8 + 2*19 = 46}}}
