Answer:

x = 2

Step-by-step explanation:

Answer:

O2

Step-by-step explanation:

5(2x-6)+20=10

Use distirbutive property:

10x-30 because, 5×2 = 10, and 5×6=30

Now we have

10x-30+20=10

Now combine the like terms

10x-10=10

Send the 10 to the other side(it turns into positive 10 because it was negative 10 on the other side)

10x = 10+10

10x=20

Divide 10 by both sides

x/10 = 20/10

x=2

Hope that helped

Complete the solution of the equation. Find the
weeeeeb [17]

Answer:  " y =  -10 . "

___________________

Step-by-step explanation:

___________________

The question:

Find the  value of  "y" when "x" equals 17.

Given the equation:

 - x + y = -27 ;

___________________

We plug in the given value: "17" ; for "x" ; and solve for "y" :

- 17 + y = -27 ;

_____________________

↔ y + (-17) = -27 ;

Rewrite as:

   y − 17  = -27 ;   {since:  "adding a negative value" is the same

                                           as "subtracting a positive value."}.

_____________________

Now, we add "17" to each side of the equation;

to isolate "y" on one side of the equation; and to solve for "y" :

  y − 17 + 17  = -27 + 17 ;

to get:

  y  =  - 10 .

Hope this is helpful to you.

Best wishes to you in your academic pursuits—

    and within the "Brainly" community!
