Find the value of x: 8x + 3 = 6x - 9

Let's break it down:

1. Combine x terms: Subtract 6x from both sides:

   8x - 6x + 3 = 6x - 6x - 9

   2x + 3 = -9

2. Combine number terms: Subtract 3 from both sides:

   2x + 3 - 3 = -9 - 3

   2x = -12

3. Isolate x: Divide both sides by 2:

   2x / 2 = -12 / 2

   x = -6

Ответ: x = -6
