### Instruction:
Several birds were sitting in the branches of a crape myrtle tree.  There were three times more cardinals than bluebirds, but half as many swallows as bluebirds. If there were 2 swallows, what is the total number of birds in the crape myrtle tree?

### Response:
 Kwa nusu ya swallows kulikuwa na bluebirds, kulikuwa na bluebirds 2*2=<<2*2=4>>4.
Kwa kadi kumi na mbili zaidi ya bluebirds, kulikuwa na kadi 3*4=12,
Ikiwa kulikuwa na swallows 2, basi idadi jumla ya ndege kwenye mti wa crape myrtle ni 2+4+12=<<2+4+12=18>>18 ndege.
