Question

-x-5>0Чему равен x? ​

Answer 1

-х-5>0

-х>0+5

-х>5

х<-5

Ответ: (-∞; -5)

Answer 2

To solve the inequality -x - 5 > 0, we need to isolate x on one side of the inequality sign. Here's how you can do it step-by-step:

1. Add 5 to both sides of the inequality: -x - 5 + 5 > 0 + 5

2. Simplify: -x > 5

3. Multiply both sides by -1 (remember that when you multiply or divide an inequality by a negative number, you need to reverse the inequality sign): -1 * (-x) < 5 * (-1)

4. Simplify: x < -5

So, the solution to the inequality is x < -5. This means any value of x that is less than -5 will make the inequality true.
