含两个未知数的方程
Equations with Two Unknowns
找出满足一个含有两个未知数的方程的数对(例如:找到数对 (a, b),使 a + b = 10 或 2a + b = 15)。
Find pairs of numbers that satisfy an equation with two unknowns (e.g. find pairs (a, b) where a + b = 10 or 2a + b = 15)
学习证据 / Evidence
- 列出所有满足 a + b = 12 且 a、b > 0 的整数数对 (a, b)。
- 找出三组满足 2x + y = 20 的数对。
- 系统地说明如何在给定范围内生成一个二元方程的所有整数解。
- List all whole-number pairs (a, b) where a + b = 12 with a, b > 0
- Find three pairs that satisfy 2x + y = 20
- Explain systematically how to generate all integer solutions to a two-variable equation within a given range
评估问题 / Assessment
{{name}}能找出几组不同的数对,让它们都满足同一条规则吗?例如,找出所有相加等于 10 的整数对。
Can {{name}} find different pairs of numbers that both satisfy a rule — for example, all the pairs of whole numbers that add up to 10?
