Need help with number 2 please

x=3 , y=-1

Step-by-step explanation:

9x-13=6x-4

9x-6x=13-4

3x=9

x=3

9y+16=4y+11

9y-4y=11-16

5y=-5

y=-1

73.0769230769% of the games were won

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
