Question

7х +4 (меньше или равно) 8х - 7

Answer 1

Решение:
7х + 4 ≤ 8х - 7
7х - 8х ≤ - 4 - 7
- х ≤ - 11
х ≥ 11
х ∈ [11; + ∞ )
Ответ: [11; + ∞).

Answer 2

7х+4<8х-7
4+7<8х-7х
11<х
х>11

Answer 3

To solve the inequality 7x + 4 ≤ 8x - 7, we need to find the range of values for x that satisfy the inequality. Let's do that:

Step 1: Move all x terms to one side of the inequality and the constant terms to the other side:

Subtract 7x from both sides: 7x - 7x + 4 ≤ 8x - 7 - 7x

Simplify: 4 ≤ x - 7

Step 2: Move the constant term to the other side:

Add 7 to both sides: 4 + 7 ≤ x

Simplify: 11 ≤ x

So, the solution to the inequality is x ≥ 11.
