Answer 1

Ответ:

Пошаговое объяснение:

3(2,4x-3,5)+6=8,7x-(9-x)

7,2x - 10,5 + 6 = 8,7x - 9 + x

7,2x - 4,5 = 9,7x - 9

9,7x - 7,2x = 9 - 4,5

2,5x = 4,5

x = 4,5 : 2,5

x = 1,8

Answer 2

To solve the equation, let's simplify and solve for x step by step:

1. Distribute the 3 to the terms inside the parentheses: 6x - 10.5 + 6 = 8.7x - (9 - x)

2. Combine like terms on both sides of the equation: 6x - 4.5 = 8.7x - 9 + x

3. Simplify the equation further by combining the x terms on the right side: 6x - 4.5 = 9.7x - 9

4. Move all the x terms to one side of the equation by subtracting 6x from both sides: 6x - 6x - 4.5 = 9.7x - 6x - 9

   Simplifying further: -4.5 = 3.7x - 9

5. Move the constant term to the opposite side by adding 9 to both sides: -4.5 + 9 = 3.7x - 9 + 9

   Simplifying further: 4.5 = 3.7x

6. Solve for x by dividing both sides of the equation by 3.7: 4.5/3.7 = (3.7x)/3.7

   Simplifying further: x ≈ 1.2162

Therefore, the solution to the equation is x ≈ 1.2162.
