x+x+x+x is equal to 4x.
4x = x + x + x + x
Explanation:
When you see x+x+x+x, you’re actually adding the value of x to itself four times.
So x+x is equal to 2x because you’re adding two equal things (two x). Similarly, x+x+x equals 3x because you’re adding three of the same thing (three x’s).
When you have x+x+x+x, it’s like adding x+x and then adding x+x again, which equals 2x+2x, or simply 4x.
So,
x+x+x+x is equal to 4x.

x+x+x+x vs x*x*x*x: Addition vs Multiplication
Adding x four times and multiplying x four times are not the same:
| Expression | Equal To | When x = 3 |
|---|---|---|
| x + x + x + x | 4x | 12 |
| x × x × x × x | x4 | 81 |
So x+x+x+x = 4x, but x*x*x*x = x4. They are equal only when x = 0 or x = ∛4 (about 1.587).
