(1)當(dāng)3x-2<0,2x+3<0,即x<-
時(shí),原式=2-3x-2x-3=-5x-1;
當(dāng)3x-2≥0,2x+3≥0,即x≥
時(shí),原式=3x-2+2x+3=5x+1;
當(dāng)3x-2≥0,2x+3<0時(shí),x不存在;
3x-2<0,2x+3≥0,即-
≤x<
時(shí),原式=2-3x+2x+3=-x+5;
(2)當(dāng)|x-1|-3≥0,3x+1≥0,①x-1≥0時(shí),|x-1|-3=x-1-3≥0,x≥4,此時(shí)原式=x-1-3+3x+1=4x-3;
②x-1<0時(shí),|x-1|-3=1-x-3>0,此時(shí)x<-2且x>-
,此時(shí)x不存在;
當(dāng)|x-1|-3>0,3x+1<0,③x-1>0時(shí),|x-1|-3=x-1-3≥0,x>4且x<-
,此時(shí)x不存在;
④x-1<0時(shí),|x-1|-3=1-x-3>0,x<-2,此時(shí)原式=-4x-3;
當(dāng)|x-1|-3<0,3x+1<0,⑤x-1≥0時(shí),|x-1|-3=x-1-3<0,x<4且x<-
,此時(shí)x無解;
⑥x-1<0時(shí),|x-1|-3=1-x-3≤0,x>-2且x<-
