Question

x-43=(57-x)-50

Answer 1

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

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

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

\(\Rightarrow2x=50\)

\(\Rightarrow x=25\)

Vậy x = 25

Answer 2

<=>x-43=(57-50)-x

<=>x-43=7-x

<=>x+x=43+7

<=>2x=50

=>x=25

Vậy x =25

Answer 3

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

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

\(x-43=7-x\)

\(x+x=7+43\)

\(2x=50\)

\(x=25\)

Answer 4

x-43=(57-x)-50

<=> x-43=57-x-50

<=> x-43=7-x

<=> x+x=7+43

<=> 2x=50

<=> x=25

Answer 5

=> x-43 = 57-x-50

=> x-43 = 7-x

=> x = 7-x+43

=> x = 50-x

=> 50 = x+x = 2x

=> x = 50 : 2 = 25
