4%5E%281-2x%29+=+32
%284%5E1%29%2A%284%5E%28-2x%29%29+=+32
4%5E%28-2x%29+=+32%2F4
4%5E%28-2x%29+=+8
2%5E%28-4x%29+=+2%5E3
-4x+=+3
x+=+-%283%2F4%29
----------------------
check
4%5E%281-2x%29+=+32
4%5E%281+-+%28-%286%2F4%29%29%29+=+32
4%5E%281+%2B+%283%2F2%29%29+=+32
4%5E%285%2F2%29+=+32
+2%5E5+=+32
32+=+32
OK
