等量关系是列方程解应用题的重要依据.一元一次方程应用题中的等量关系通常有哪些呢?下面结合例题归纳出十类常见的等量关系,供同学们学习时参考:第一类:相遇问题相遇问题中的等量关系:甲(从A出发)所走的路程+乙(从B出发)所走的路程=A、B两地间的路程.在求解时,应注意灵活运用公式:路程=速度×时间.例1 A、B两地相距700千米,甲车从A出
Isometric relationship is an important basis for solving the column equation solution problem.Unified equivalent equation in the application of a dollar equation is usually what? The following combination of examples to infer ten common isometric relations for students to learn reference: the first Category: Encounter Problems Equivalence in encounter problems: Distance traveled by A (starting from A) + Distance traveled by B (starting from B) = Distance traveled between A and B. When solving, care should be taken Using the formula: distance = speed × time.Example 1 A, B two 700 km apart, A car from A out
