=200 nha bạn

Ai tich mik mik tích cho , mik có nhiều nick lắm.

264 + { -64} =+ {264-64} =+200.Tick nha

\(264-\left(3\times x+155\right)=64\)

\(3\times x+155=264-64\)

\(3\times x+155=200\)

\(3\times x=200-155\)

\(3\times x=45\)

\(x=\frac{45}{3}=15\)

264 - ( 3x + 155 ) = 64

3x + 155 = 264 - 64 

3x + 155 = 200

3x = 200 - 155

3x = 45

x = 45 : 3

x = 15

264 - (3 * x + 155 ) = 64

      ( 3 * x + 155 ) = 264 - 64

      ( 3 * x + 155 )= 200

       3 * x = 200-155

       3 * x=45

          x = 45 : 3

          x = 15

264-86+386-64= 500

thi tốt nha

(264+386)-(86+64)

=650-150

=500

=264-64+386-86

=200+300

=500

=9000 nha bn

cac bn ung ho nhe!

=45 x (264-64)

= 9000

264 x 45 - 45 x 64

= 45 x ( 264 - 64 )

= 45 x 200 = 9000 k tớ nha

a) `1/2 xx 5/4 + 1/2 xx 3/4 + 1/2`

`=1/2 xx (5/4 + 3/4 + 1)`

`=1/2 xx 3`

`=3/2`

b) `72/95 xx 64/72 xx 95/72 xx 14/86 xx 72/64 xx 86/14`

`=(72xx64xx95xx14xx72xx86)/(95xx72xx72xx86xx64xx14)`

`= 1`.

a)1/2.(5/4+3/4+1)

=1/2.3

=3/2

b)=(72/95.95/72).(64/72.72/64).(14/86.86/14)

=1.1.1=1

6193 - [ 72 . ( x - 104 ) + 98 ] = 5807

72 . ( x - 104 ) + 98 = 6193 - 5807

72 . ( x - 104 ) + 98 = 386

72 . ( x - 104 ) = 386 - 98

72 . ( x - 104 ) = 288

x - 104 = 72 . 288 

x - 104 = 20736

x = 20736 + 104 

x = 20840

6193-[72.(x-104)+98]=5807

72.(x-104)+98=6193-5807

72.(x-104)+98=386

72.(x-104)=386-98

72.(x-104)=288

x-104=288.72

x-104=20736

x=20736+104

x=20840
