Question

70,5+57x=56,75+62,5x​

Answer 1

Ответ:

x= 2,5

Пошаговое объяснение:

70,5+57x=56,75+62,5x​

57x-62,5x= 56,75-70,5

-5,5x = -13,75

5,5x = 13,75

x= 13,75 : 5,5

x= 2,5

Проверка:

70,5+57*2,5 = 56,75+62,5*2,5

70,5+142,5 = 56,75+156,25

Answer 2

To solve for the value of x in the equation:

70.5 + 57x = 56.75 + 62.5x

You want to isolate x on one side of the equation. You can do this by performing the following steps:

1. First, let's get all the terms containing x on one side of the equation and constants on the other side. To do this, subtract 62.5x from both sides of the equation:

70.5 + 57x - 62.5x = 56.75 + 62.5x - 62.5x

This simplifies to:

70.5 - 62.5x + 57x = 56.75

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

(57x - 62.5x) = (57 - 62.5)x = -5.5x

3. Rewrite the equation with the combined terms:

-5.5x + 70.5 = 56.75

4. Now, subtract 70.5 from both sides of the equation to isolate -5.5x:

-5.5x + 70.5 - 70.5 = 56.75 - 70.5

-5.5x = -13.75

5. Finally, divide both sides by -5.5 to solve for x:

(-5.5x) / (-5.5) = (-13.75) / (-5.5)

x = 2.5

So, the solution to the equation is:

x = 2.5
