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+y2
y = 4
x + x+2 + y = 12
2x + 6 = 12
x = 3
sides : 3, 4, and 5
