### Instruction:
Susan loves chairs. In her house there are red chairs, yellow chairs, and blue chairs. There are 5 red chairs. There are 4 times as many yellow chairs as red chairs, and there are 2 fewer blue chairs than yellow chairs. How many chairs are there in Susan's house?

### Response:
There are 5 x 4 = <<5*4=20>>20 yellow chairs.
There are 20 - 2 = <<20-2=18>>18 blue chairs.
There are 5 + 20 + 18 = <<5+20+18=43>>43 chairs in Susan's house.
