Question

8x-3(x+9) больше или равно -9

Answer 1

8x-3x-27>= -9; 8x-3x>= -9+27; 5x>=18; x>=3,6. Ответ: x>=3,6. [3,6:+бесконечность).

Answer 2

To solve the inequality 8x - 3(x + 9) ≥ -9, follow these steps:

Step 1: Distribute the -3 on the left side of the inequality: 8x - 3(x + 9) = 8x - 3x - 27

Step 2: Combine like terms on the left side: 8x - 3x - 27 = 5x - 27

Step 3: Now, the inequality becomes: 5x - 27 ≥ -9

Step 4: Add 27 to both sides of the inequality to isolate the variable term: 5x - 27 + 27 ≥ -9 + 27

Simplified inequality: 5x ≥ 18

Step 5: Finally, divide both sides by 5 to solve for x: x ≥ 18 / 5

The solution for the inequality is x ≥ 3.6.
