2(x+y)=24
2x=y
Use substitution. If y=2x, than we can substitute 2x for it in the other equation, because x and y equal the same things in both equations.
So using that we get 2(x+2x)=24
SIMPLIFY
2(3x)=24
DISTRIBUTE
6x=24.
DIVIDE: x=4.
If we substitute x into the original equations we get x=4 and y=8. Those are your two numbers.
Have a nice day! :)

Answer: I think it is 47.23
Step-by-step explanation: Because 25% of 14.99 = 11.2425 But 35.99+11.2425 dose not seem right so I pretty sure it would be 35.99+11.24= 47.23
