The perimeter of a triangle is 24 cm. One side is 2 cm longer than the shortest side. The longest side is 2 cm less than twice the length of the shortest side. Find the length of each side of the triangle.- write equation and solve.

• pre- algebra -

Let x = shortest side

24 = x + (x + 2) + (2x - 2)
24 = 4x
24/4 = x
6 = x

Sum of all three sides is perimeter

Let length of shortest side be x

Other sides becomes (x+2) and (2x-2)

X+(x+2)+(2x-2)=24
4x=24
X=6
