Question

2,5(4-x)+5(x-1,3)=4,5+2,5xСРОООЧНООО​

Answer 1

$2,5*(4-x)+5*(x-1,3)=4,5+2,5x$

$10-2,5x+5x-6,5=4,5+2,5x$

$-2,5x+5x-2,5x=4,5-10+6,5$

$0x=1$  

$x=1:0$    Но на 0 делить нельзя, поэтому данное уравнение не имеет корней.

Ответ:  {∅}

Answer 2

To solve the equation $2.5(4-x) + 5(x-1.3) = 4.5 + 2.5x$, you can follow these steps:

1. Distribute the terms on both sides of the equation to eliminate parentheses.
2. Combine like terms on each side.
3. Move all terms involving $x$ to one side of the equation and constants to the other side.
4. Simplify the equation to solve for $x$.

Let's go through the steps:

$$\begin{align*} &2.5(4 - x) + 5(x - 1.3) = 4.5 + 2.5x \\ &10 - 2.5x + 5x - 6.5 = 4.5 + 2.5x \quad \text{(Distribute)} \\ &2.5x - 2.5 = 4.5 + 2.5x \quad \text{(Combine like terms)} \\ &2.5x - 2.5 - 2.5x = 4.5 \quad \text{(Move constants to the other side)} \\ &-2.5 = 4.5 \quad \text{(Combine like terms)} \\ \end{align*}$$

The equation $-2.5 = 4.5$ is not true, which means there is no solution to the original equation. In other words, the given equation is inconsistent.
