(x-1)/(x+2)>(x-1)/4x+12,(x-1)/(x+2)-(x-1)/4(x+3)>0,4(x-1)(x+3)-(x-1)(x+2)/4(x+2)(x+3)>0,×4(x+2)的平方(x
(5x-1)/3-x>1(5x-1)-3x>32x>4x>2
(x-1)/3《(3-x)/22(x-1)《3(3-x)2x-2《9-3x5x《11x《2.2x=1;x=2
由①不等式解得x<25/7由②不等式解得x≥-1所以解集为-1≤x<25/7很高兴为您解答,【学习宝典】团队为您答题.请点击下面的【选为满意回答】按钮,
5x-1>3(x+1)5x-1>3x+32x>4x>22分之1x-1>3-2分之3x1/2x-1>3-3/2x2x>4x>2x-1-2x>-1所以解集的公共部分是x>2
解不等式,2(2x–5)–6>3x–184x–10–6>3x–184x–3x>10+6–18x>–2所以负整数解是–1
去分母,得6x-5x+3<0移项,得6x-5x<-3合并同类项,得x<-3
4x-2y=-1①x+4y=2②①×2,得8x-4y=-2③②+③,得9x=0x=0y=1/2x/2<2(x-1)两边乘2,得x<4x-4x<4/3x/3>(x+2)/5两边乘15,得5x>3(x+2
解;3x-(x+2)/4>(2x-5)/672x-6(x+2)>4(2x-5)72x-6x-12-8x+20>058x>-8x>-4/291-x/5≤x/1515-3x≤x-4x≤-15x≥15/4

阳光下的青睐:(x-5)/2+1>x-3(x-5)/2>x-4x-5>2(x-4)x-5>2x-8x-2x>-8+5-x>-3x
两边同乘以十再算,结果是x大于十三分之十五
1:解不等式组得x≤(7-根号74)/10或≤(7+根号74)/10≤x
2-x>0(1)(2分之5x+1)+1》3分之2x-1(2)由(1)得x4x-615x+3+6>4x-611x>-15x>-15/11∴-15/11
再答:是这个题目吗?再答:再问:不是,是(2x减3)分之(x加1)小于0再答:。。。再答:等我一会儿再问:嗯嗯再答:
2x-x/3+1<02x-x/3
自己看看数学书一定会
5x-1>3(x+1)1/2x-13+11/2x+3/2x42x2x3(x+1)与二分之一x-1
5x-2m>-4-x6x>2m-4x>(2m-4)/62分之x-3<3x+1同乘以2,得x-3-5x>-1(2m-4)/6=-1(2m-4)=-62m=-2m=-1
