Was the "w" a typo and supposed to be "x"?



It must be identically true when x = any number.  
So it must be true when x=0. So we substitute x=0







, divide through by 4



It must also be true when x=1. So we substitute x=1







, divide through by 4



So we have the system



This is an inconsistent system, so there is no solution.  That is,
if you copied it correctly and the "w" is correct.  There would be
a solution, however, if "w" was supposed to be "x".
