Question 778177
Let {{{ x }}} = amount invested @ 5%
{{{ x + 2000 }}} = amount invested @ 6%
His annual interest is:
{{{  .05x + .06*( x + 2000 ) = 670 }}}
{{{  .05x + .06x + 120 = 670 }}}
{{{  .11x = 550 }}}
{{{ x = 5000 }}}
{{{ x + 2000 = 7000 }}}
$5,000 was invested @ 5%
$7,000 invested @ 6%
-------------------
check:
{{{  .05x + .06*( x + 2000 ) = 670 }}}
{{{  .05*5000 + .06*7000 = 670 }}}
{{{ 250 + 420 = 670 }}}
{{{ 670 = 670 }}}
OK
