Question

In sakura’s garden, for every 5 red flowers, there are 10 yellow flowers. There are a total of 75 yellow and red flowers in her garden. How many ref flowers are in Sakura’s garden?

Answer 1

The first thing we must do for this case is to define variables.
 We have then:
 x: number of red flowers
 y: number of yellow flowers.
 We write the system of equations:
 x + y = 75
 y = 2x
 Solving the system we have:
 x = 25
 y = 50
 Answer:
 there are 25 red flowers in Sakura's garden
