Answer:
x = 5
Step-by-step explanation:
Let's picture this.
The length of each side is (x+1), and since they are all equal to each other, we can assume this shape is a square.
Perimeter is the length of all the sides added up, which means that we can write it out like this:
24= (x+1) + (x+1) + (x+1) + (x+1)
Then, we can add up the variables that are the same, which means our equation turns into:
24 = 4x + 4
Then, we subtract 4 from both sides:
20 = 4x
Finally, to get x, we divide by 4 on both sides.
x = 5
