Answer 1

$25x - 15 - 25x - 15 = - 30 \\ - 30 = - 30$

Ответ : x - любое число. х Є (-∞;+∞)

Answer 2

Let's solve the equation step by step:

1. Distribute the multiplication on both sides of the equation: 5 * (5x - 3) - 5 * (5x + 3) = -30 25x - 15 - (25x + 15) = -30

2. Simplify the equation by combining like terms on the left side: 25x - 15 - 25x - 15 = -30

3. Combine the terms: (25x - 25x) - (15 + 15) = -30 0 - 30 = -30

4. Simplify further: -30 = -30

The equation is true for any value of x, which means it is an identity and holds true for all real numbers. So, the solution to the equation is all real numbers.
