Answer:
x-y=2.5,xy=21
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
One of the numbers is x.
The other number is y.
The difference between two numbers is 2.5
This means that x - y = 2.5
The product of those two numbers is 21.
This means that xy = 21.
So the two equations are: x-y=2.5,xy=21
X=alice
b=barry
c=charlene
x=15 more than b
x=15+b
c=2 times of b
c=2b
all together
x+c+b
15+b+2b+b
15+4b
they have 15+4b or 15+4 times of barry
if we want in terms of x
x=15+b
x-15=b
15+4(b)
15+4(x-15)
15+4x-60
4x-45
they have 4x-45 together
