Question

9(x - 12) + 2x = 4x + 2(x - 4)​

Answer 1

Ответ:

9(x - 12) + 2x = 4x + 2(x - 4)

9x - 108 + 2x = 4x + 2x - 8

9x + 2x - 4x - 2x = -8 + 108

9x - 4x = -8 + 108

5x = 100

x = 20

Answer 2

To solve the equation 9(x - 12) + 2x = 4x + 2(x - 4), follow these steps:

1. Distribute the constants outside the parentheses:

   9x - 108 + 2x = 4x + 2x - 8

2. Combine like terms on both sides of the equation:

   9x + 2x - 108 = 4x + 2x - 8

   11x - 108 = 6x - 8

3. Move the 6x term to the left side by subtracting 6x from both sides of the equation:

   11x - 6x - 108 = -8

   5x - 108 = -8

4. Add 108 to both sides of the equation to isolate the variable term:

   5x - 108 + 108 = -8 + 108

   5x = 100

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

   (5x)/5 = 100/5

   x = 20

So, the solution to the equation is x = 20.
