**Answer This Question**

Need help making this easier

Roses = 3u

Tulips = 5u

3u roses - 5u tulips = 66

Roses sold = 1u

Tulips sold = 3u

3u tulips - 1u roses = 74

So 9u tulips - 3u roses = 74 x 3 = 222

3u roses = 9u tulips - 222 ①

From above, we know

3u roses - 5u tulips = 66

Using the result from 1, this becomes

9u tulips - 222 - 5u tulips = 66

4u tulips = 66 + 222 = 288

1u tulips = 288 ÷ 4 = 72

3u roses = 9 x 72 - 222 = 426

1u roses = 426 ÷ 3 = 142

From here you can find the required answers

3 x 5 = 15

So, let tulips = 15 u

Then roses = 15u + 66

1/3 of roses = (15u + 66) ÷ 3 = 5u + 22

3/5 of tulips = 3/5 x 15u = 9u

9u - (5u + 22) = 74

4u - 22 = 74

4u = 74 + 22 = 96

1u = 96 ÷ 4 = 24

Tulips left = 15u - 9u = 6u

6u = ?

Roses left = 15u + 66 - 5u - 22

= 10u + 44

10u + 44 = ?

And the number of tulips left should be 6u instead of 9u. 9u is the number of tulips sold.

Some error in the calculations. Will correct it soon.
