Isolating s, the equation written in terms of s is:

-------------------------
- The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

- To solve for the lengths of the congruent sides, we isolate s, thus:
