Find the value of x: 5x + 3 = x - 1

Here's how we solve this one:

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

   5x - x + 3 = x - x - 1

   4x + 3 = -1

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

   4x + 3 - 3 = -1 - 3

   4x = -4

3. Isolate x: Divide both sides by 4:

   4x / 4 = -4 / 4

   x = -1

Ответ: x = -1
