Question

7x + 10 = 5x + 15 решите уравнение

Answer 1

Ответ:

2.5

Пошаговое объяснение:

$7x + 10 = 5x + 15 \\ 2x = 5 \\ x = 2.5$

Answer 2

To solve the equation 7x + 10 = 5x + 15, you need to isolate the variable x on one side of the equation. Here's how you can do it step by step:

1. Get all the x terms on one side and constants on the other side. Subtract 5x from both sides: 7x + 10 - 5x = 5x + 15 - 5x

   Simplify the equation: 2x + 10 = 15

2. Now, get rid of the constant term on the left side of the equation. Subtract 10 from both sides: 2x + 10 - 10 = 15 - 10

   Simplify the equation: 2x = 5

3. Finally, isolate x by dividing both sides by the coefficient of x (which is 2): 2x / 2 = 5 / 2

   Simplify the equation: x = 2.5

So the solution to the equation is x = 2.5.
