Question 846334
Let {{{ x }}} = the number of elephants
that were ill
{{{ x + 300 }}} = the total number of elephants
The number that were ill was:
{{{ (1/3)*( x + 300 ) }}}
{{{ (1/3)*x + 100 }}}
Now I can say:
{{{ x = (1/3)*x + 100 }}}
{{{ (2/3)*x = 100 }}}
{{{ 2x = 300 }}}
{{{ x = 150 }}}
150 elephants were ill
There were {{{ x + 300 = 150 + 300 }}}
{{{ 150 + 300 = 450 }}}
450 elephants total
