------------------------------------------------
2.
find four consecutive even integers such that four times the fourth decreased by one half the second is 9.
-----------------------------------------------


n, for any integer

The integers,  n-4,n-2,n,n+2

{{{4(n+2)-(1/2)(n-2)=9}}}
-
{{{8(n+2)-(n-2)=18}}}
{{{8n+16-n+2=18}}}
{{{7n=0}}}
{{{n=0}}}


The consecutive even integers:
-4, -2, 0, 2
