已知x满足不等式:4-2(x-4)<3(x-1),化简|6-2x|-|2x-1|
问题描述:
已知x满足不等式:4-2(x-4)<3(x-1),化简|6-2x|-|2x-1|
答
4-2(x-4)<3(x-1)
4-2x+8<3x-3
3x+2x>8+4+3
5x>15
x>3
|6-2x|-|2x-1|
= -(6-2x)-(2x-1)
=-6+2x-2x+1
=-5
祝学习进步,望采纳~~
答
4-2(x-4)<3(x-1),
4-2x+8-2x-3x-5xx>3
|6-2x|-|2x-1|
=2|3-x|-|2x-1|
=2(x-3)-(2x-1)
=2x-6-2x+1
=-5
答
4-2(x-4)<3(x-1)
4-2x+8
