Answer:

#329+658 = 987# roses altogether

Explanation:

There are 2 unknowns - the number of red roses and the number of white roses.
You can use one variable to define both of them
He sold fewer white roses, choose this as #x#

Let the number of white roses be #x#.
The number of red roses is #2x" "larr# twice as many as white roses

Each white rose costs $10 and each red rose costs $8

#10x+8xx2x =8554#

#10x+16x = 8554#

#26x= 8554#

#x = 8554/26#

#x=329# white roses

#2x = 2xx329=658#red roses

#329+658 = 987# roses altogether
