Answer:
let x be the number of roses and y the number of daisies
x+y= 9 ( flowers)
3*x will be the cost of the roses
2*y will be the cost of daisies
then 3x+2y= 25 $ ( the cost of the 9 flowers)
therefore the 2 equations
x+y= 9
3*x+ 2*y= 25
solution of the two equations:
we multiply the 1st equation by 2
2x+ 2y= 18
3x+2*y= 25
2nd equation minus 1st equation we will have:
x= 7 therefore y=2

The answer is in the media.Good luck!
2x-2/8-3x/5 =55/4 distributive property of multiplication over subtraction
(10x-3x)/5-1/4=55/4 combining like terms
7x/5-1/4+1/4=55/4+1/4 addition propriety of equality
7x/5=56/4 add fractions
X=5•56/7•4=280/28=10
