You can put this solution on YOUR website!
%28x%2B2%29%2B%282x%2B3%29%2B5x=21 to account for perimeter.
8x%2B5=21
8x=16
x=2

"x=2" is part way toward the finished solution. I do not say that x=2 is THE solution. You could finish the solution yourself by using x, now known, to evaluate the segment lengths of your given expressions.
