Question

12(4+x) = 4+x-17;2x+10 =?​

Answer 1

Ответ:

12(4+x)=4+x-17

48+12x=x-13

12x-x=-48-13

11x=-61

x=-61/11

x=-5 6/11

-122/11+10=-11 1/11+10=-1 1/11

Answer 2

To solve the equation 12(4+x) = 4+x-17, you'll want to simplify and isolate the variable x:

1. Distribute the 12 on the left side of the equation:

12(4+x) = 4+x-17 48 + 12x = 4 + x - 17

2. Now, combine like terms on the right side of the equation:

48 + 12x = 4 + x - 17 48 + 12x = x - 13

3. Next, move all terms involving x to one side of the equation and constants to the other side:

48 - x = x - 13 - 12x

4. Simplify further:

48 - x = -11x - 13

5. Add x to both sides of the equation to isolate the x terms:

48 - x + x = -11x - 13 + x

6. This simplifies to:

48 = -10x - 13

7. Add 13 to both sides of the equation:

48 + 13 = -10x - 13 + 13

8. Simplify further:

61 = -10x

9. Finally, divide both sides by -10 to solve for x:

61 / -10 = -10x / -10

x = -6.1

So, the solution for the equation is x = -6.1.

Now, to find 2x + 10:

2x + 10 = 2(-6.1) + 10 = -12.2 + 10 = -2.2
