I’m so confused. Is there any other part to the question?
Answer: x=2

Hope this helps you out! ☺
The perimeter is all sides length added together. You can make an equation:5+5+x+x where x is the length.
5+5=10 18-10=8 There is two sides so you do eight divided by two
The length is 4
Move all terms that don’t contain m to the right side and solve. M = 3
