Question

4,6*(x+4,4)=8,4*(3x+5,1)

Answer 1

Решение: Раскрываем скобки, получаем

4,6x+20,24=25.2x+42.84

Неизвестные собираем в левой части уравнения, известные в правой части уравнения. (при переносе слагаемых из одной части в другую знак «+» меняем на “ –“, а знак “ – “  на «+».), получаем

4.6х-25.2х=42.84-20.24

В каждой части уравнения приводим подобные слагаемые, получим

-20.6 х=22.6

Неизвестное ищем, как неизвестный множитель ( произведение делим на известный множитель), получаем

Х=22.6\(-20.6)=-226\206=-113\103

Овтет: -113\103

Answer 2

4,6х+20,24=25,2х+42,84

4,6х-25,2х=42,84-20,24

-20,6х=22,6

х=22,6:(-20,6)

х=-1,097

Answer 3

Sure! Let's solve the equation step by step:

Step 1: Distribute the multiplication on both sides of the equation.

On the left side, we have: 4.6 * x + 4.6 * 4.4

On the right side, we have: 8.4 * 3x + 8.4 * 5.1

The equation becomes: 4.6x + 20.24 = 25.2x + 42.84

Step 2: Simplify the equation by combining like terms.

We have two terms with x, so let's move them to one side of the equation. We can do this by subtracting 4.6x from both sides:

4.6x - 4.6x + 20.24 = 25.2x - 4.6x + 42.84

This simplifies to: 20.24 = 20.6x + 42.84

Step 3: Move the constant term to the other side by subtracting 42.84 from both sides:

20.24 - 42.84 = 20.6x + 42.84 - 42.84

This simplifies to: -22.6 = 20.6x

Step 4: Solve for x by dividing both sides of the equation by 20.6:

(-22.6) / 20.6 = (20.6x) / 20.6

This simplifies to: -1.097 = x

So the solution to the equation 4.6*(x+4.4) = 8.4*(3x+5.1) is x = -1.097.
