Answer 1

Ответ:

4

Пошаговое объяснение:

(3х + 15) : 9 = 3

3х + 15 = 3 * 9

3х + 15 = 27

3х = 27 - 15

3х = 12

х = 12 : 3

х = 4

Answer 2

To solve the equation (3x + 15) ÷ 9 = 3, we can follow these steps:

1. Subtract 15 from both sides of the equation to isolate the term with x: (3x + 15) ÷ 9 - 15 = 3 - 15 (3x + 15) ÷ 9 - 15 = -12

2. Simplify the left side of the equation: (3x + 15) ÷ 9 - 15 = -12 (3x + 15) ÷ 9 = -12 + 15 (3x + 15) ÷ 9 = 3

3. Multiply both sides of the equation by 9 to get rid of the fraction: 9 * ((3x + 15) ÷ 9) = 3 * 9 3x + 15 = 27

4. Subtract 15 from both sides of the equation: 3x + 15 - 15 = 27 - 15 3x = 12

5. Divide both sides of the equation by 3 to solve for x: (3x)/3 = 12/3 x = 4

Therefore, the solution to the equation (3x + 15) ÷ 9 = 3 is x = 4.
