x+x+x+x is equal to 4x.
4x=x+x+xx
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.
