Step-by-step explanation:
<u><em>The question in English is</em></u>
Find 2 numbers knowing that the second number is 7 times greater than the first, and the sum between the double of the first number and the triple of the second is 460
Define the variables
Let
x ----> the first number
y ----> the second number
we know that
-----> equation A
----> equation B
Solve the system of equations by substitution
Substitute equation A in equation B
![2x+3(7x)=460](https://tex.z-dn.net/?f=2x%2B3%287x%29%3D460)
solve for x
![2x+21x=460](https://tex.z-dn.net/?f=2x%2B21x%3D460)
![23x=460](https://tex.z-dn.net/?f=23x%3D460)
![x=20](https://tex.z-dn.net/?f=x%3D20)
<em>Find the value of y</em>
