a: |3x-5|+|2x+3|=7(1)

TH1: \(x<-\frac32\)

=>2x+3<0; 3x-5<0

(1) sẽ trở thành: \(-2x-3-3x+5=7\)

=>-5x+2=7

=>-5x=5

=>x=-1(loại)

TH2: \(-\frac32\le x<\frac53\)

=>2x+3>=0; 3x-5<0

(1) sẽ trở thành: 2x+3-3x+5=7

=>8-x=7

=>x=1(nhận)

TH3: \(x\ge\frac53\)

=>2x+3>0; 3x-5>=0

(1) sẽ trở thành: 2x+3+3x-5=7

=>5x-2=7

=>5x=9

=>\(x=\frac95\) (nhận)

b: |x|+|x+2|=3(2)

TH1: x<-2

=>x+2<0; x<0

(2) sẽ trở thành: -x-2-x=3

=>-2x=5

=>\(x=-\frac52\) (nhận)

TH2: -2<=x<0

=>x+2>=0; x<0

(2) sẽ trở thành x+2-x=3

=>2=3(vô lý)

TH3: x>=0

=>x+2>0; x>=0

(2) sẽ trở thành: x+2+x=3

=>2x+2=3

=>2x=1

=>\(x=\frac12\) (nhận)

c: |3x-5|=|x+2|

=>\(\left[\begin{array}{l}3x-5=x+2\\ 3x-5=-x-2\end{array}\right.\Rightarrow\left[\begin{array}{l}2x=7\\ 4x=3\end{array}\right.\Rightarrow\left[\begin{array}{l}x=\frac72\\ x=\frac34\end{array}\right.\)

= (37,5.6,5 + 3,5.37,5) – (7,5.3,4 + 6,6.7,5)

= 37,5(6,5 + 3,5) – 7,5(3,4 + 6,6)

= 37,5.10 – 7,5.10

= 375 – 75 = 300

= ( 37,5 . 6,5 + 3,5 . 37,5 ) – ( 7,5 . 3,4 + 6,6 . 7,5 )

= 37,5 . ( 6,5 + 3,5 ) – 7,5 ( 3,4 + 6,6 )

= 37,5 . 10 – 7,5 . 10

= 375 – 75

= 300
