The flower shop sold roses and tulips. the number of roses sold was 5 less than twice the number of tulips sold. if the shop sold 106 flowers in total, how many of each kind of flowers were sold?

the number of roses sold is 69 while number of tulips is 37

Step-by-step explanation:

Let x represent the number of roses that the flower shop sold.

Let y represent the number of tulips that the flower shop sold.

The number of roses sold was 5 less than twice the number of tulips sold. This means that

x = 2y - 5 - - -- -- - - - - - ;1

If the shop sold 106 flowers in total, it means that

x + y = 106

Substituting x = 106 - y into equation 1, it becomes

106 - y = 2y - 5

3y = 106 + 5 = 111

y = 111/3 = 37

x = 106 - y = 106 - 37

x = 69

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

- (2, -7)

- lines r and s and lines t and u must be parallel
