Answer 2

Answer:

number of trousers=14

numbers of pairs of stockings=71

Step-by-step explanation:

Pairs of stockings: x

T shirt: y

Trouseres: z

7x=3y

1z=1y+2×

__________________________________________

m: number of trousers

m*z=26y

m*(y+2x)=26y

m*(y+2(3y/7))=26y

m=26y/(y+2(3y/7))

m=14

You need to buy 14 trousers that represents the equivalent of 26 T-shirts.

k:pairs of stockings

k*x=10y+11z

k*x=10(7x/3)+11(y+2x)

k*x=10(7x/3)+11((7x/3)+2x)

k=71

You need to buy 71 pairs of stockings with an amount equal to the price of 10 T-shirts and 11 trousers
