(x-2)/3-(3x+5)/2>=(2-x)/(x-3),通分得(-7x-19)/6>=(2-x)/(x-3),移项,通分,化简得(7x^2-8x-45)/(x-3)
5分之3x-7<2分之x-23X/5-7
(x-2)/3-(3x+5)/2>=(2-x)/(x-3),通分得(-7x-19)/6>=(2-x)/(x-3),移项,通分,化简得(7x^2-8x-45)/(x-3)
解不等式组2x+3>3x3分之x+3-6分之x-1≥2分之1由2x+3>3x得x
2分之x+2>(3分之2x-1)-2x3x+6>4x-2-12x;11x>-8;x>-8/11;手机提问的朋友在客户端右上角评价点【满意】即可.
x+2>0,x+2>(3x+14)/55x+10>3x+14x>2x+2(3x+14)/5-5x-10>3x+14x
解一元一次不等式x-4>3(x-2)x-4>3x-6;2x<2;x<1;3分之2x+1
去分母,得6x-5x+3<0移项,得6x-5x<-3合并同类项,得x<-3
3/8(x+1)-1>(x-5)/2-x3/8x+x/2>-5/2+1-3/87/8x>-3/2-3/8x>-15/7
①-3(x-2)≥4-x-3x+6≥4-x-3x+x≥4-6-2x≥-2x3x-36x-3x>-3-13x>-4x>-4/3再问:阿阿,--第二个不等式是这样的1+2x------->x-13再答:1

3(x+2)>4x+23x+6>4x+24x-3x2x-2x>-2所以-2
2分之(3x-1)>2x3x-1>4x-x>1x2x再答:(2分之3)x-1>2x1.5x-1>2x-0.5x>1x
去分母:6-2(x-1)≤3(2x+3-x)去括号:6-2x+2≤6x+9-3x移项:6+2-9≤6x-3x+2x合并同列项:-1≤5x系数化为1:-5分之1≤x
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
2分之x>2+xx>4+2xx
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
两边乘以10得10x-5(3x-4)
1-(3-x)/(x+2)>0(x+2-3+x)/(x+2)>0即(2x-1)(x+2)>0x1/2
4x-21>5x-84-x>-63x<63
