Question

9x-6(x-1)=5(x+2)....​

Answer 1

Ответ: х=-2

Объяснение:

9х-6х+6=5х+10

3х+6=5х+10

-2х=4

х=-2

Answer 2

Ответ:

9 * x - 6 * ( x - 1 ) = 5 * ( x + 2 ) ;

9 * x - 6 * x + 6 = 5 * x + 10 ;

x * ( 9 - 6 ) + 6 = 5 * x + 10 ;

3 * x + 6 = 5 * x + 10 ;

Известные значения переносим на одну сторону, а неизвестные на другую сторону. При переносе значений, их знаки меняются на противоположный знак. То есть получаем:

3 * x - 5 * x = 10 - 6 ;

- 2 * x = 4 ;

x = - 4 / 2 ;

x = - 2 ;

Answer 3

To solve the equation 9x - 6(x - 1) = 5(x + 2), you'll want to simplify and then isolate the variable x. Here are the steps to solve it:

1. Distribute the constants outside the parentheses on both sides of the equation:

   9x - 6x + 6 = 5x + 10

2. Combine like terms on each side:

   (9x - 6x) + 6 = 5x + 10

   3x + 6 = 5x + 10

3. Now, you want to isolate the variable x on one side of the equation. Start by moving the 3x term to the right side by subtracting 3x from both sides:

   3x - 3x + 6 = 5x - 3x + 10

   6 = 2x + 10

4. Next, subtract 10 from both sides of the equation:

   6 - 10 = 2x + 10 - 10

   -4 = 2x

5. Finally, divide both sides by 2 to solve for x:

   (-4) / 2 = (2x) / 2

   -2 = x

So, the solution to the equation 9x - 6(x - 1) = 5(x + 2) is x = -2.
