Four mathematical formulas
Solution: Suppose the first rope is x meters long, then the second rope is (48.4-x) meters long. According to the meaning of the question, the equation can be listed as: (x-6.4) * 2+6 = 48.4-x 2x-12.8+6 = 48.4-x 3x = 55.2x =18.4, and the length of the second article is 48.4-/kloc-0. study hard
