Answer :
Answer: The numbers are 14 2/3 and 43 1/3 (you can also write it as 44/3 and 130/3)
Step-by-step explanation:
x+y=58
2y-4x=28
This is a system of equations, so you can make the y equal to each other by: 2x+2y=116
Now you can subtract the equations from each other, so you have
2x+2y=116
-(2y-4x)=28
The y cancels out, leaving you with 6x=88, so x=14 2/3
When you plug x in, you get y=43 1/3
