Question

8-(x-10)=23-(-4+12)

Answer 1

8-(x-10)= 23 -(-4+12)

8-x+10=23+4-12

8 - x + 10 = 15

8 - x = 15 - 10 = 5 

=> x = 8 - 5 

   x = 3 

Vậy x = 3 

Answer 2

\(8-\left(x-10\right)=23-\left(-4+12\right)\)

\(8-x+10=23+4+12\)

\(18-x=39\)

\(x=-21\)

Answer 3

8-(x-10)=23-(-4+12)

8-(x-10)=15

x-10=8-15

x-10=-7

Vậy x=-7+10=3

Answer 4

    8-(x-10)=23-(-4+12)

=>8-(x-10)=23-8

=>8-(x-10)=15

=>x-10      =8-15

=>x-10      = (-7)

=>x=(-7)+10

=>x=3

Vậy x=3

Answer 5

Sorry lm lại:

\(8-\left(x-10\right)=23-\left(-4+12\right)\)

\(8-x+10=23+4-12\)

\(18-x=15\)

\(x=3\)

Answer 6

8 - ( x - 10 ) = 23 - ( -4 + 12 )

=> 8 - x + 10 = 23 + 4 - 12

=> 8 + 10 - 23 - 4 + 12 = x 

=> 3 = x

Vậy : x = 3
