Kenya picked 18 flowers from her garden. If 3/5 flowers in her garden remain unpicked, how many flowers are still in her garden?

Let the total number of flowers be x and remaining flowers be y

x-18 = (3/5) x

x - ((3/5) * x) - 18 = 0

x + (-3/5) * x-18 = 0

2/5*x-18 = 0

2/5*x = 18

x = 18/2/5

x = 45

total flowers = 45

plucked flowers = 18

remaining flowers = y = 45-18 = 27
