Question 1018996
Let {{{ x }}} = number of fiinches he started with
He then bought 2 pairs, so he has
{{{ x + 4 }}} finches
------------------
He then gave 6 away, so he has:
{{{ x + 4 - 6 }}}
---------------
Then he lost 3/4 of the finches, so he has:
{{{ (1/4)*( x + 4 - 6 ) }}}
---------------
And now he has 13 finches so,
{{{ ( 1/4)*( x - 2 ) = 13 }}}
Multiply both sides by {{{ 4 }}}
{{{ x -2 = 52 }}}
{{{ x = 54 }}}
He started with 54 finches
