124 : x + 24 : x - 48 : x = 25

(124 + 24 - 48) : x = 25

100 : x = 25

x = 100 : 25 

x = 4

124 : x cộng 24 :x trừ 48 :xbằng 25

`#3107.101107`

\(48\div24-x=1\\ \Rightarrow2-x=1\\ \Rightarrow x=2-1\\ \Rightarrow x=1\)

Vậy, `x = 1`

____

\(124-2\times\left(x+3\right)=24\\ \Rightarrow2\left(x+3\right)=124-24\\ \Rightarrow2\left(x+3\right)=100\\ \Rightarrow x+3=100\div2\\ \Rightarrow x+3=50\\ \Rightarrow x=50-3\\ \Rightarrow x=47\)

Vậy, `x = 47.`

1) 48 : 24 - x = 1                               2) 123 - 2 x (x+3) = 24

    2-x=1                                                 2 x (x+3) = 123 - 24   

       x= 2-1                                             2 x (x+3) = 99

       x= 1                                                       x+3 = 99 : 2

                                                                     x+3 = \(\dfrac{99}{2}\)

                                                                     x     = \(\dfrac{99}{2}\) -3

124 x 25 + 24 x 124 + 50 + 124

= 124 x 25 + 50 ( 24 + 1 )

= 124 x ( 25 + 50 + 25 )

= 124 x 100

= 124000

Nhìn mà mún lòi cả con mắt hà

a) 137 x 7 + 137 x 93
= 137 x ( 93 + 7 )
= 137 x 100 = 13700

b) 428 x 102 - 428 x 2
= 428 x ( 102 - 2 )
= 428 x 100
= 42800

c) 124 x 25 - 25 x 24
= 25 x ( 124 - 24 )
= 25 x 100 
= 2500

_HỌC TỐT_
 

a) 137 x 7 + 137 x 93

\(=137\times\left(7+93\right)\\ =137\times100\\ =13700\)

b) 428 x 102 - 428 x 2

\(=428\times\left(102-2\right)\\ =428\times100\\ =42800\)
c) 124 x 25 - 25 x 24

\(=25\times\left(124-24\right)=\\ 25\times100=2500\)
