Question

9х - 5 (х - 1) = 6 (х + 2);

Answer 1

Ответ:

Объяснение:

9х - 5 (х - 1) = 6 (х + 2)

9x-5x+5=6x+12

9x-5x+5-6x-12=0

-2x-7=0

-2x=7

x= -3.5

Answer 2

To solve the equation 9x - 5(x - 1) = 6(x + 2), follow these steps:

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

   9x - 5x + 5 = 6x + 12

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

   (9x - 5x) + 5 = 6x + 12

   4x + 5 = 6x + 12

3. Move the 4x term to the right side of the equation by subtracting 4x from both sides:

   4x - 4x + 5 = 6x - 4x + 12

   5 = 2x + 12

4. Now, subtract 12 from both sides of the equation to isolate the variable x:

   5 - 12 = 2x + 12 - 12

   -7 = 2x

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

   (-7)/2 = (2x)/2

   -7/2 = x

So, the solution to the equation 9x - 5(x - 1) = 6(x + 2) is x = -7/2.
