Answer 2

Раскрываем скобки
5х+7-(2х+5)=3,5+2х
5х+7-2х-5=3,5+2х
перенгсим х вправо, остальные цифры влево, при этом меняя знак
5х-2х-2х=-7+5+3,5
Х=1,5

Answer 3

Let's solve the equation step-by-step:

1. Distribute the numbers outside the parentheses: 2(2x + 3) - 2(x + 2.5) = 3.5 + 2x

2. Perform multiplication inside the parentheses: 4x + 6 - 2x - 5 = 3.5 + 2x

3. Combine like terms on both sides of the equation: (4x - 2x) + (6 - 5) = 3.5 + 2x

Simplifying further: 2x + 1 = 3.5 + 2x

4. Now, we need to get all the x terms on one side of the equation, so let's subtract 2x from both sides: 2x + 1 - 2x = 3.5 + 2x - 2x

Simplifying further: 1 = 3.5

5. Since the equation simplifies to 1 = 3.5, it means there is no solution for this equation. In other words, the equation is inconsistent, and there are no values of x that satisfy the equation.

Therefore, the original equation 2(2x + 3) - 2(x + 2.5) = 3.5 + 2x has no solution.
