简化 X2 + 10x + 22 = 6 重新排序条件: 22 + X2 + 10x = 6 解: 22 + X2 + 10x = 6 求解变量 'X'. 移动所有含x 的放右边,所有其它条件放左边. 增加 '-22' 到方程的每一侧. 22 + X2 + -22 + 10x = 6 + -22 重新排序条件: 22 + -22 + X2 + 10x = 6 + -22 结合相似条件: 22 + -22 = 0 0 + X2 + 10x = 6 + -22 X2 + 10x = 6 + -22 结合相似条件: 6 + -22 = -16 X2 + 10x = -16 增加 '-10x' 到方程的每一侧. X2 + 10x + -10x = -16 + -10x 结合相似条件: 10x + -10x = 0 X2 + 0 = -16 + -10x X2 = -16 + -10x 简化 X2 = -16 + -10x 重新排序条件: 16 + X2 + 10x = -16 + -10x + 16 + 10x 重新排序条件: 16 + X2 + 10x = -16 + 16 + -10x + 10x 结合相似条件: -16 + 16 = 0 16 + X2 + 10x = 0 + -10x + 10x 16 + X2 + 10x = -10x + 10x 结合相似条件: -10x + 10x = 0 16 + X2 + 10x = 0 无法确定此方程的解.
