Kaya is a hairdresser. Before her lunch break, she gave 2 haircuts and colored the hair of 1 client in 93 minutes. After lunch, she gave 3 haircuts and colored the hair of 1 client in 108 minutes. How long does it take for Kaya to perform each type of service, assuming the amount of time doesn't vary from client to client?

2 haircut and 1 hair colour = 93 min

3 haircut and 1 colour  = 108 min

Let haircut be represented by variable x and hair color be represented by variable y.

2x + 1y = 93....................1)

3x + 1y = 108.................. 2)

Subtract 1 from 2.

X = 15............hence time for haircut is = 15 min.

Y = 63...........hence time for hair colour is = 63 min.
