Answer 2

Ответ:

Пошаговое объяснение:

6⋅(5x−9)−5⋅(6x+9)=−99

30х - 54 - 30х - 45 = -99

-99 = -99

Answer 3

To solve the equation 6(5x - 9) - 5(6x + 9) = -99, you can follow these steps:

1. Distribute the numbers outside the parentheses to the terms inside the parentheses:

6 * 5x - 6 * 9 - 5 * 6x - 5 * 9 = -99

2. Perform the multiplications:

30x - 54 - 30x - 45 = -99

3. Combine like terms:

(30x - 30x) - 54 - 45 = -99

0x - 99 = -99

4. Simplify the equation:

0 - 99 = -99

-99 = -99

The equation is true. So, this equation has an infinite number of solutions, which means any value of x will satisfy the equation. In other words, it's an identity.
