Question

关于x的方程5x-6=3(x+k)的解是非负数,求k的取值范围？急急急~

Answer 1

5x-6=3(x+k)
5x-6=3x+3k
5x-3x=3k+6
2x=3k+6
x=1.5k+3
∵枯迹谨解是州郑非没基负数
∴1.5k+3≥0
∴k≥-2

Answer 2

5x-6=3x+3k
5x-3x=3k+6
2x=3k+6
x=3k+6/2
∵是非负数
∴3k+6/2≥0
3k+6≥0
3k≥做和历棚慧-6
k≥-2
希望纯搜能帮到你~~

Answer 3

5x - 6 = 3x + 3k
2x = 3k + 6

x = 3k/2 + 3
3k/2 + 3 ≥念正 0
k ≥御高枣镇拆 - 2

Answer 4

5倍，6 = 3（X + K）
5倍，6 = 3X +3 K

5倍，3倍= 3K +6

2X = 3K +6

X = 1.5K +

∵伏租解决缺指兆非逗滚负

∴1.5K +3≥0∴K表
≥-2
