Question

The difference between two numbers is 5.

Twice one number and 4 times another
number gives 34.
What are the two numbers?

Answer 1

9 and 4

Explanation:

let one number be X and the other y

so that x-y=5 and 2x+4y= 34

by using SIMULTANEOUS EQUATION

2x-2y= 10

2x+4y= 34. eliminate x values by subtraction

to be -6y = -24

so y = 4

use any of the equation now to get value of x

I use first equation

x-y= 5

so if why is 4 then automatically x is 9.

I hope you are helped!
