Answer 1

Ответ:

12-5х-5=7+5х

7-5х=7+5х

-5х=5х

-5х-5х=0

-10х=0

х=0

Answer 2

12-5х-5= 7+3х+2х
-5х-3х-2х=7-12-5
-10х=-10
х=-10\-10
х=1

Answer 3

To solve for the variable x in the equation "12 - 5(x + 1) = 7 + 3x + 2x," you need to simplify and isolate x. Here are the steps to solve it:

1. Start by simplifying both sides of the equation:

   12 - 5(x + 1) = 7 + 3x + 2x

   12 - 5x - 5 = 7 + 5x

2. Next, combine like terms on each side of the equation:

   12 - 5 - 5x = 7 + 5x

   7 - 5x = 7 + 5x

3. Now, get the variable terms on one side and the constant terms on the other side. To do this, you can add 5x to both sides of the equation:

   7 - 5x + 5x = 7 + 5x + 5x

   7 = 7x

4. Finally, solve for x by dividing both sides by 7:

   (7 / 7) = (7x / 7)

   1 = x

So, the solution to the equation is x = 1.
