Read this problem. A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Find the length of each side of the triangle.
What equation represents the perimeter of the triangle if the second side is length s?

3s = 165
(2s - 65) + (s - 10) = 165
(2s + 65) + (s) + (s + 10) = 165
(2s - 65) + (s) + (s - 10) = 165
