Question

9 - 25 = ( 7 - x ) - ( 25 + 7 )

làm rõ cho mình nhá

ai đúng tick

Answer 1

\(9-25=\left(7-x\right)-\left(25+7\right)\)

\(7-x-25-7=-16\)

\(0-x-25=-16\)

\(0-x=9\)

\(\Rightarrow x=-9\)

Answer 2

9 - 25 = ( 7 - x ) - ( 25 + 7 )

-16   = ( 7 - x ) - 32

-16 + 32 =7 - x

Answer 3

\(9-25=\left(7-x\right)-\left(25+7\right)\Rightarrow-16=\left(7-x\right)-32\Rightarrow-\left(7-x\right)=-32+16\)

\(\Rightarrow-7+x=-16\Rightarrow x=-16+7\Rightarrow x=-9\)

Answer 4

9 - 25 = ( 7 - x ) - ( 25 + 7 )

    - 16 = ( 7 - x ) - 32 

-16 + 32 = 7 -  x 

       x = 7 -16 

       x = -9

Answer 5

     9 - 25  = ( 7-x ) - ( 25 + 7 )

=> 9 - 25 = 7 - x - 25 - 7

=>     x    = 7 - 25 - 7 - 9 + 25

=>     x    =         -9
