giúp mình với các bạn ơi

x-43=(57+2x)-50

Answer 1

\(x-43=\left(57+2x\right)-50\)

\(x-2x=57-50+43\)

\(-x=50\)

\(x=-50\)

Answer 2

x-43=57+2x-50

=>x=-50

Answer 3

=> x-43 = 57+2x-50

=> x-43 = 2x+7

=> 2x = x-43-7 = x-50

=> 50 = x-2x = -x

=> x = 50 : (-1) = -50

Vậy x = -50

Tk mk nha

Answer 4

x - 43 = ( 57 + 2x ) - 50

x - 43 = 2x + 7

x - 2x = 7 + 43

-x = 50

x = -50

Answer 5

x-43=(57+2x)-50

x-43+50=57+2x

x+7=57+2x

x-2x=57-7

-x=50

\(\Rightarrow\)x=-50

vậy x=-50

nhớ k cho mk nha.

=>x = -50
