Leanne works at a greenhouse She needs to plant a total of 3

Leanne works at a greenhouse. She needs to plant a total of 32 bulbs. Two types of bulbs are available. She is asked to plant three times as many crocus bulbs as tulip bulbs. how many of each should she plant?

Solve this using substitution of elimintation!!

Solution

Two types of bulbs are available

Let no. of crocus bulbs be x

Let no. of tulip bulbes be y

She is asked to plant three times as many crocus bulbs as tulip bulbs

y = 3x ---> y-3x =0 (1)

Total 32 bulbs:

x+y = 32 (2)

Solve equation 1 and 2 :

y-3x =0

x+y = 32

------------- ( subtract)

-3x -x = -32

4x = 32

x= 8 nos of crocus bulbes

y = 3x = 24 nos of tulip bulbs
