Question

5x-18≤3(x+2) решите неравенство

Answer 1

5x-18≤3(x+2) 
5x-18≤3x+6
5x-3x≤6+18
2x≤24
x≤24:2
x≤12
x∈(-∞;12]

Answer 2

To solve the inequality 5x - 18 ≤ 3(x + 2), we will follow these steps:

1. Distribute the 3 on the right side: 5x - 18 ≤ 3x + 6.
2. Subtract 3x from both sides: 5x - 3x - 18 ≤ 6. Simplifying, we get: 2x - 18 ≤ 6.
3. Add 18 to both sides: 2x - 18 + 18 ≤ 6 + 18. Simplifying, we get: 2x ≤ 24.
4. Divide both sides by 2 (the coefficient of x): (2x) / 2 ≤ 24 / 2. Simplifying, we get: x ≤ 12.

Therefore, the solution to the inequality is x ≤ 12.
