Final answer:
In the bouquet, the number of red and yellow tulips is equal to the number of tulips.
Step-by-step explanation:
In the bouquet, there were 48 flowers. Of these, x were tulips. Of the tulips, y were red and z were yellow. We need to find the values of y and z.
Since the total number of flowers in the bouquet is 48, we can set up the equation x + (48 - x) = 48, where (48 - x) represents the number of non-tulip flowers. Simplifying this equation, we get x = 48 - x, which means that y + z = 48 - x.
We are given that x = 48 - x, so we can substitute this in the previous equation, which gives us y + z = 48 - (48 - x). Simplifying further, we get y + z = x.
Therefore, the number of red and yellow tulips in the bouquet is x.
