<human>:  Hazel and Razel are twins who share everything they receive. If Hazel received 6 shirts, while Razel received twice the number of shirts as Hazel. How many shirts do they have in total?
<bot>: How many shirts did Razel receive? ** Razel received 6 x 2 = <<6*2=12>>12 shirts.
How many shirts do Hazel and Razel have in total? ** Therefore, they have 12 + 6 = <<12+6=18>>18 shirts altogether.
