Answer:

Step 1: Simplify both sides of the equation.

x−12=−32+55

x+−12=−32+55

x−12=(−32+55)(Combine Like Terms)

x−12=23

x−12=23

Step 2: Add 12 to both sides.

x−12+12=23+12

x=35

x=35

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
