B nha bạn

Chọn D nha

a. |a| = 12

=> a = 12 hoặc a = -12

b. |a| = |-12|

=> |a| = 12 => a = 12 hoặc a = -12

c. |a + 2| = 0

=> a + 2 = 0 => a = -2

d. -17|a| = -85 => |a| = 5 => a = 5 hoặc a = -5

e. |a| = -16 (vô no vì trị của 1 số luôn > 0)

a)\(\left|a\right|=12\)

\(\Rightarrow\orbr{\begin{cases}a=12\\a=-12\end{cases}}\)

b)\(\left|a\right|=\left|-12\right|\)

\(\Rightarrow\left|a\right|=12\)

\(\Rightarrow\orbr{\begin{cases}a=12\\a=-12\end{cases}}\)

c)\(\left|a+2\right|=0\)

\(\Rightarrow a+2=0\)

\(\Rightarrow a=-2\)

d)\(-17.\left|a\right|=-85\)

\(\Rightarrow\left|a\right|=\frac{-85}{-17}=5\)

\(\Rightarrow\orbr{\begin{cases}a=5\\a=-5\end{cases}}\)

e) \(\left|a\right|=-16\)(Vô lí )

Tìm x :

a) 35 + 3. |x| = 50

3.|x|=50-35

3.|x|=15

|x|=15:3

|x|=5

x=5 hoặc x=-5

 

b)72 - [41 - (2x - 5) ]- 23.5

41-(2x-5)=72-40

41-(2x-5)=32

2x-5=41-32

2x-5=9

2x=9+5

2x=14

x=14:2

x=7

c) 70 - 5 (x - 3) = 45

5(x-3)=70-45

5(x-3)=25

x-3=25:5

x-3=5

x-5+3

x=8
