The side of an equilateral triangle is 2 inches shorter than the side of a
square. The perimeter of the square is 30 inches more than the perimeter
of the triangle. Find the length of a side of the triangle.
------
Let each side of the square be "x"
Then each side of the triangle is "x-2":
-----
Equation:
4x = 3(x-2)+30
4x = 3x-6+30
x = 24 (each side of the square)
x-2 = 22 (each side of the triangle)
