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+%2B+1.5x+%2B+1.5x+-+2+=+214+
+4x+-+2+=+214+
+4x+=+216+
+x+=+54+
and
+1.5x+=+1.5%2A54+
+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
