How to set up a proportion with this information ?

Question

Dwayne has two kinds of flowers in his garden: dandelions and tiger lilies. Dwayne planted only tiger lilies, but dandelions came up too. There are 55 flowers in his garden, and there are 19 more dandelions than tiger lilies. How many of the flowers are tiger lilies?

Answer 1

You, again. Hello person :)

 

Let d represent the number of dandelions

Let l  represent the number of lilies 

 

1) l+ d= 55                He has a total of 55 flours

2) d= l+ 19                He has 19 more dandelions than lilies

 

Now, I am going to substitute l+19 for d into equation #1 above.

 

1) l + d = 55

   l + (l+ 19)= 55                Combining like terms

      2l + 19  = 55

            -19     -19

              2i      = 36.           Dividing by 2

                l=  18

He has 18 lilies and 37 dandelions.
