Question

9(х-3)=5(х+5) решить уровнение

Answer 1

Ответ:

Х = 13

Пошаговое объяснение:

9Х - 27 = 5Х + 25

9Х - 5Х = 27 + 25

4Х = 52

Х = 52 : 4 = 13

проверяем:

9 (13 - 3) = 5 (13 + 5)

90 = 90

Answer 2

9(x-3)=5(x+5)

9х-27=5х+25

9х-5х=25+27

4х=52

Х=13

Answer 3

To solve the equation 9(x-3) = 5(x+5), we'll need to find the value of x that makes the equation true. Here are the steps to solve it:

1. Distribute the terms on both sides of the equation: 9x - 27 = 5x + 25

2. Move all the x terms to one side of the equation and the constants to the other side: 9x - 5x = 25 + 27

3. Combine like terms: 4x = 52

4. Solve for x by dividing both sides by the coefficient of x (which is 4 in this case): x = 52 / 4 x = 13

So the solution to the equation is x = 13.
