Question

4,5(Х—1) –2,3(Х = 2) = 2,1 Х

Answer 1

Уравнение:

4,5(Х-1)–2,3(Х-2)=2,1Х

Ответ:

$-(\frac{23x}{10}-\frac{23}{5})+\frac{9(x-1)}{2}=\frac{21x}{10}$

x = -1

Решение:

Линейное уравнение:

(9/2)*(x-1)-(23/10)*(x-2) = (21/10)*x

Раскрываем скобки сначала в левой части, а затем и в правой части уравнения:

1) 9/2x-1-23/10x-2 = 21/10*x

2) 1/10+11*x/5=21/10x

Переносим свободные слагаемые(те, которые без икса) из левой части в правую, получаем

11x/5 = (21x/10)-(1/10)

x/10 = -10

Обе части делим на 1/10

x = -1/10 / (1/10)

Получаем наш ответ: x = -1.

Answer 2

Ответ:

х=91

Пошаговое объяснение:

4,5х - 4,5 - 2,3х=4,6=2,1х

4,5х-2,3х-2,1х= 4,5 + 4,6

0,1х=9,1

х=9,1:0,1

х=91

Answer 3

It looks like you've provided an equation with some expressions involving variables. However, there seem to be some formatting issues in your equation, and it's not entirely clear what you're asking. Let's try to clarify the equation and solve it step by step.

If the equation is:

4.5(X - 1) - 2.3(X + 2) = 2.1X

We can proceed with solving it:

Step 1: Distribute the numbers to the terms inside the parentheses:

4.5X - 4.5 - 2.3X - 4.6 = 2.1X

Step 2: Combine like terms on the left side of the equation:

(4.5X - 2.3X - 2.1X) - (4.5 + 4.6) = 0

-0.9X - 9.1 = 0

Step 3: Add 9.1 to both sides of the equation to isolate the variable term:

-0.9X = 9.1

Step 4: Divide both sides by -0.9 to solve for X:

X = -10.11

So, the solution for the equation is X = -10.11. Please double-check the original equation and the calculations to ensure accuracy, as there might have been some formatting errors in your initial input.
