Flowerbed

On the flowerbed was planted 280 flowers - pansies and crayons. During the first week wilts quarter of pansies and an eighth crayons, which is 20% of all flowers.

How many pansies were planted on the flowerbed?

Result

x =  168

Solution:

x+y=280 14x+18y=20100280x+y=280 \ \\ \dfrac{1}{4}x+\dfrac{1}{8}y = \dfrac{ 20}{100} \cdot 280

x+y=280
1/4*x+1/8*y = 20/100*280

x+y = 280
50x+25y = 11200

x = 168
y = 112
