5.2 là 5 nhân 2 hay 5 phẩy 2

x+5,2-(32+16.3:16-5)=0

(=)x+5,2-30=0

(=)x+5,2=30

x=24,8

chúc bạn học tốt ^_^

a) 460 + 85 * 4 = ( x + 200 ) * 4

460 + 340 = ( x + 200 ) * 4

800 = ( x + 200 ) * 4

x + 200 = 200

x = 0

b) x + 5 * 2 - ( 32 + 16 * 3 : 16 - 15 ) = 0

x + 10 - ( 32 + 3 - 15 ) 0

x + 10 - 20 = 0

x - 10 = 0

x = 10

a) \(460+85.4=\left(x+200\right).4\)

\(\Rightarrow460+340=4x+800\)

\(\Rightarrow-4x=800-460-340\)

\(\Rightarrow-4x=0\)

\(\Rightarrow x=0\)

Vậy x = 0

b) \(x+5.2-\left(32+16.3:16-15\right)=0\)

\(\Rightarrow x+10-\left(32+3-15\right)=0\)

\(\Rightarrow x+10-20=0\)

\(\Rightarrow x-10=0\)

\(\Rightarrow x=10\)

Vậy x = 10

a, \(460+85.4=\left(x+200\right)4\)

\(460+340=\left(x+200\right)4\)

\(800=\left(x+200\right)4\)

\(\Leftrightarrow x+200=\frac{800}{4}\)

\(\Leftrightarrow x+200=200\)

\(\Rightarrow x=200-200\)

\(\Rightarrow x=0\)

Vậy \(x=0\)

x + 10 - (32 + 48 : 6 - 15) = 0

x + 10 - (32 + 8 - 15)       = 0

x + 10 - 25                     = 0

x                                   = 0 + 25 - 10

x                                  =15

bay gio mk ranh rui mk lam cho

x+5.2-(32+16.3:6-15)=0

x+5.2-(32+48:6-15)   =0

x+5.2-(32+6-15)        =0

x+5.2-(38-15)            =0

x+5.2-23                   =0

x+10-23                    =0

x+10                         =0+23

x+10                         =23

                              x=23-10

                              x=13

chuc bn hoc gioi!

x+5.2-(32+16:3x6-15)=0

=> x+ 5+10-(32:32-15)=0

=> x+ 15- (-14)=0

=>x+15 +14=0

=> x= 0-14-15

=>x= -29

25 nhé bạn

ý lộn 15 nhé bạn

dài quá ko làm nha!!!

\(\Leftrightarrow\)\(5x+10-25=0\)

\(\Leftrightarrow\)\(5x=15\)

\(\Leftrightarrow\)\(x=\frac{15}{5}=3\)
