2(x - 1) + 3 = x - 3(x + 1)
2x - 2 + 3 = x - 3x - 3
2x + 1 = - 2x - 3
2x + 1 = - 2x - 3 + 2x
4x + 1 = - 3
4x = 1 - 1 = - 3 - 1
4X = - 4
4x / 4 = - 4 / 4
x = - 1

2(x-1)+3=x-3(x+1)?
Perhaps it is required to solve this equation. Then :
2x - 2 + 3 = x - 3x - 3 or
2x - x + 3x = -3 + 2 - 3 or
4x = - 4 which leads to
x = -1. Answer.
Verified the answer. Ok

2(x - 1) + 3 = x - 3(x + 1)
2x - 2 + 3 = x - 3x - 3
2x + 1 = -2x - 3 (Add 2x and subtract 1 from both sides)
4x = -4 (Divide both sides by 4)
x = -1
Check:
2(-1 - 1) + 3 = -1 - 3(-1 + 1)
2(-2) + 3 = -1 - 3(0)
-4 + 3 = -1 - 0
-1 = -1

2x - 2 + 3 = x - 3x -3
2x + 1 = -2x -3
2x + 2x = -3 -1
4x = -4
x = -1
Solution: {there is x in R | x = -1}
