Question

100x + x - 50x + 100 - 50x = 100 . tìm x

Answer 1

( 100x - 50x - 50x ) + x + 100 = 100

=>             x + 100 = 100

=>            x = 0

Answer 2

Ta có: 100x + x - 50x + 100 - 50x = 100

=> (100x + x - 50 - 50x) + 100 = 100

=> x + 100 = 100

=> x = 100 - 100

=> x = 0

Answer 3

100x + x - 50x + 100 - 50x=100

<=>(100x-50x-50x)+x=100-100

<=>x=0

Vay x=0

Answer 4

100x + x - 50x + 100 - 50x = 100

( 100x - 50x - 50x ) + x + 100 = 100

0 + x + 100 = 100

x + 100 = 100

x = 100 - 100

x = 0.
