Hebrew和他儿子的年龄总和是51岁,3年前,父亲的年龄是儿子的8倍,问现在儿子的岁数?
Let x be the current age of Hebrew's son and 51-x be the current age of Hebrew.
51-x-3=8(x-3)
48-x=8x-24
-9x=-72
x=8
The current age of Hebrew's son is 8.

意思就是说某人和他儿子年龄加起来是51.3岁，他是他儿子年龄的八倍，求他儿子的年龄
设他儿子年龄是x，那么他的年龄就是8x
9x=51.3
x=5.7

大意为：一个人和他儿子总共51岁 3年前是这个人年龄是他儿子的8倍
知道意思应该非常简单了
设这个人儿子3年前的年龄为X岁 根据题意得
x+3+8x+3=51
解之得
x=5
题目中要求现在儿子的年龄 所以为5+3=8（岁）

他和他儿子年龄的总和是51岁，3年前 父亲的年龄是儿子的8倍，问现在儿子的岁数

设他儿子的岁数现在是x岁 则父亲是51-x
根据3年前的关系列方程 (51-x-3)=8(x-3)
48-x=8x-24
