The sum of two numbers is 58. Twice the second number subtracted to four times the first number is 28. Find the two numbers. ​

Sagot :

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
