Question 1154005
Let {{{ x }}} = thousands of cars recycled 1st year
{{{ 6300 - x }}} = thousands of cars recycled 2nd year
------------------------
{{{ 6300 - x = x + 700 }}}
{{{ 2x = 5600 }}}
{{{ x = 2800 }}} thousand
and
{{{ 2800 + 700 = 3500 }}} thousand
----------------------------
2.8 million were recycled the 1st yr
3.5 million were recycled the 2nd yr
( converted to millions )
