Nathan AxelTo solve the equation -8 - x = x - 4x:
- Combine like terms: -8 - x = x - 4x becomes -8 - x = (1 - 4)x
- Simplify the right side: -8 - x = -3x
- Add 3x to both sides: -8 - x + 3x = -3x + 3x
- Simplify: -8 + 2x = 0
- Add 8 to both sides: -8 + 2x + 8 = 0 + 8
- Simplify: 2x = 8
- Divide both sides by 2: 2x/2 = 8/2
- Simplify: x = 4
So, the solution to the equation is x = 4.
