Question

Tìm x:

(27-x)+(15+x)=x-24

 

Answer 1

(27-x)+(15+x)=x-24

27-x+15+x=x-24

27+15+24=x+x-x

42+24=2x-x

66=x

vậy x=66

Answer 2

27-x + 15 + x = x - 24

=> 42 = x - 24

=> x = 24 + 42 = 66

Answer 3

( 27 - x ) + ( 15 + x ) = x - 24

<=> 27 - x + 15 + x = x - 24

<=> 42 = x - 24

<=> x = 66

Answer 4

(27 - x) + (15 + x) = x - 24

=> 27 - x + 15 + x = x - 24

=> x - 24 = 42

=> x = 66

vậy_
