Step-by-step explanation:
15 : 25 : 40
So first we will divide it by 5
3 : 5 : 8
We cannot further divide it so it is the simplest form
X=2y
2x+5y=9
substitute the x=2y into the second equation
2(2y)+5y=9
multiple the 2y by 2. 4y+5y=9
combine like terms. 9y=9
divide the 9 out from both sides. y=1
plug the y back into the first equation
x=2(1)
multiply. x=2
your answer is: x=2
y=1
