Question

9x = 749 + 2x 7x=749 9.728x + 7.272x = 4.08 17x = 4.08

Answer 1

Ответ:

9x = 749 + 2x

7x=749

x=107

9.728x +7x =4.08

17x = 4.08

x=0,24

Answer 2

It seems like you have a series of equations. Let's analyze each one separately:

1. 9x = 749 + 2x: To solve this equation, we can start by simplifying it. Subtracting 2x from both sides, we get: 9x - 2x = 749. Simplifying further, we have: 7x = 749.

2. 7x = 749: This equation appears to be the result of the previous step. To solve for x, we can divide both sides by 7: 7x/7 = 749/7, which simplifies to: x = 107.

3. 9.728x + 7.272x = 4.08: Combining the like terms on the left side of the equation, we have: 17x = 4.08.

4. 17x = 4.08: To solve for x, we can divide both sides by 17: 17x/17 = 4.08/17, which simplifies to: x ≈ 0.24.

In summary:

• The solution to the equation 9x = 749 + 2x is x = 107.
• The solution to the equation 9.728x + 7.272x = 4.08 is x ≈ 0.24.
