Asked by BRYAN
A florist had 66 more stalks of roses than tulips. She sold 1/3 of the roses and 3/5 of the tulips. She sold 74 more tulips than roses.
How many roses and tulips did she have left?
Thanks for your help.

r = t+66
(1/3 r) + 74 = 3/5 t
r = 426 and t = 360
So finish it off
(1/3 r) + 74 = 3/5 t
r = 426 and t = 360
So finish it off

Could you please tell me where r=426? and t=360 come from?

solve those two equations!
(1/3 r) + 74 = 3/5 t
multiply by 15 to clear fractions
5r + 15*74 = 9t
9t-5r = 1110
r = t+66, so
9t-5(t+66) = 1110
4t-330 = 1110
4t = 1440
t = 360
(1/3 r) + 74 = 3/5 t
multiply by 15 to clear fractions
5r + 15*74 = 9t
9t-5r = 1110
r = t+66, so
9t-5(t+66) = 1110
4t-330 = 1110
4t = 1440
t = 360
