Question

x- 43 = ( 57- x ) -50

giúp mình với

Answer 1

x-43= (57-x)-50

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

<=>2x= 50

=> x= 50/2= 25

Answer 2

x-43=(57-x)-50

x-43=57-x-50

x+x =57-50+43

2x =7+43

2x =50

x =50:2

x =25

Vậy x=25

Answer 3

x-43 = (57-x ) -50

x-43 = 57- x- 50

x + x= 57 - 50+43

2x =7+43

2x = 50

x = 50 :2

x = 25

Vậy x= 25
