Use the fact that +log%28+10+%29+=+1+
+log%28+x%2B6+%29+-+log%28+10+%29+=+log+%28+x+-+3+%29+
+log%28+x%2B6+%29+-+log%28+x-3+%29++=+log%28+10+%29+
+log%28+%28+x%2B6+%29%2F%28+x-3+%29+%29++=+log%28+10+%29+
+%28+x%2B6+%29%2F%28+x-3+%29+=+10+
+x+%2B+6+=+10%2A%28+x-3+%29+
+x+%2B+6+=+10x+-+30+
+9x+=+36+
+x+=+4+
---------
check:
+log%28+x%2B6+%29+-+log%28+10+%29+=+log+%28+x+-+3+%29+
+log%28+4%2B6+%29+-+log%28+10+%29+=+log+%28+4+-+3+%29+
+log%28+10+%29+-+log%28+10+%29+=+log%28+1+%29+
+1+-+1+=+0+
+0+=+0+
OK
