Question 1106030
Let {{{ x }}} = the average life expectancy of South Africa
{{{ 1.5x }}} = the average life expectancy of Norway
{{{ 1.5x - 2 }}} = the average life expectancy of Germany
----------------------------------------------------
{{{ x + 1.5x + 1.5x - 2 = 214 }}}
{{{ 4x - 2 = 214 }}}
{{{ 4x = 216 }}}
{{{ x = 54 }}}
and
{{{ 1.5x = 1.5*54 }}}
{{{ 1.5x = 81 }}}
and
{{{ 1.5x -2 = 79 }}}
-----------------------
The average life expectancy of South Africa is 54
The average life expectancy of Norway is 81
The average life expectancy of Germany is 79
