Question

При каком значении переменной x значение выражения -2x−12 равно 2?

Answer 1

$-2x-12=2\\-2x=2+12\\-2x=14\\x=14:(-2)\\x=-7$ Ответ: при x=-7 данное выражение равно 2

Answer 2

-2*(-7)-12=2
- на - = -
(14-12=2)

Answer 3

To find the value of the variable x when the expression -2x - 12 is equal to 2, we need to solve the equation:

-2x - 12 = 2

Let's solve for x:

Step 1: Add 12 to both sides of the equation to isolate the term with x on the left side.

-2x = 2 + 12

Step 2: Simplify the right side of the equation.

-2x = 14

Step 3: Divide both sides by -2 to solve for x.

x = 14 / -2

x = -7

So, when x is equal to -7, the expression -2x - 12 will be equal to 2.
