Answer:

The numbers are 20 and 140

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

$y=7x$ -----> equation A

$2x+3y=460$ ----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B

$2x+3(7x)=460$

solve for x

$2x+21x=460$

$23x=460$

$x=20$

<em>Find the value of y</em>

$y=7x$ ----> $y=7(20)=140$

The numbers are 20 and 140
