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
