Two sides of a triangle have the same length. the third side measures 6 m less than twice the common length. the perimeter of the triangle is 22 m. what are the lengths of the three sides?

Let x be the common length. Then, the sides of the triangle are x, x, and 2x-6. These three sides sum up to 22, so you have

So, the two equal sides are 7m long, and the third side is
