You can put this solution on YOUR website!
Let +d+ = the number of dolls
+%281%2F3%29%2A18+%2B+%281%2F6%29%2A18+%2B+d+=+18+
+6+%2B+3+%2B+d+=+18+
+d+=+18+-+9+
+d+=+9+
She has 9 dolls
check:
+%281%2F3%29%2A18+%2B+%281%2F6%29%2A18+%2B+9+=+18+
+%281%2F3%29%2A18+%2B+%281%2F6%29%2A18+=+9+
Multiply both sides by +6+
+36+%2B+18+=+54+
+54+=+54+
OK
