Question

Jacinski’s Hardware has some bikes and tricycles for sale. There are 27 seats and 60 wheels all together.
Determine how many bikes there are and how many tricycles there are.

Answer 1

Step-by-step explanation:

2x+3y=60 (2wheels for bike and 3 for tricycle)->1

x+y=27-->2

multiple 2equation with 2

2x+2y=54

2x+3y=60

- - -

_______

-y=-6

y=6 so substitute y in equation 2

x+6=27

x=21

so bikes 21 and tricycles 6

Answer 2

Answer:

bikes - 21, tricycles - 6

Step-by-step explanation:

bike - X

tricycle- Y

2x + 3y = 60

x= 27-y

2(27-y) + 3y = 60

54 - 2y +3y = 60

54 + y =60

y= 6

x= 27 - 6

x = 21
