Sammy Bridges · Answer 1

1small bus=12

large bus=24

total passengers is 780

total busses is 20

# of small bus = x

# of large bus=y

so x+y=20

every one x=12 people so

780=12x+24y

the 2 equations are

x+y=20

12x+24y=780

Store sells wheels in pachages of 2 and 3

40 packs and 100 wheels

1 pack of 2 = 2 so

# of 2 pack=x

# of 3 pack=y

x+y=40

2x+3y=100

those are the 2 equations
