Question

x-43= (57-x)-50

tìm x

Answer 1

Ta có : x - 43 = ( 57 - x ) - 50

x - 43 = 57 - x - 50

x = 57 - 50 + 43 - x

x = 50 - x

x + x = 50

2x = 50

x = 50 : 2

x = 25

Vậy x = 25

Answer 2

1 câu ngắn gọn =25

Answer 3

Ta có : \(x-43=\left(57-x\right)-50\)

\(\Rightarrow x-43=57-x-50\)

\(\Rightarrow x+x=57-50+43\)

\(\Rightarrow2x=50\)

\(\Rightarrow x=50:2\)

\(\Rightarrow x=25\)

Vậy x=25

Answer 4

Ta có :

x - 43 = ( 57 - x ) - 50

=> x - 43 = 57 - x - 50

=> x + x = 57 - 50 + 43

=> 2x = 50

=> x = 50 : 2

=> x = 25

Vậy x = 25
