Question 1137913
Let {{{ x }}} = the cost of the DVD player
{{{ 3x }}} = the cost of the television
--------------------------------------------
{{{ x + 3x = 1104 }}}
{{{ 4x = 1104 }}}
{{{ x = 276 }}}
and
{{{ 3x = 828 }}}
The DVD player costs $276
The TV costs $828
--------------------------------
check:
{{{ x + 3x = 1104 }}}
{{{ 276 + 828 = 1104 }}}
{{{ 1104 = 1104 }}}
OK
