The perimeter of a triangle is equal to 12 inches. The length of the longest side is equal to the sum of the other two sides minus 2. If you add 2 to the shortest side, it will equal the longest side. Find the side lengths.

let .. shortest side ---- x longest side ---- x+2 middle side ----- y "The length of the longest side is equal to the sum of the other two sides minus 2" x+2 = x+y-2 y = 4 x + x+2 + y = 12 2x + 6 = 12 x = 3 sides : 3, 4, and 5
