Answer 2

x=51-12=39

x=65-23=42

Answer 3

Tìm \(x\):

a) \(x+12=51\)

\(x=51-12\)

\(x=39\)

b) \(65-x=23\)

\(x=65-23\)

\(x=42\)

Answer 4

a, x + 12 = 51

    x         = 51 - 12

    x         = 39 

Vậy x = 39

b, 65 - x = 23

          x = 65 - 23

          x = 42 

Vậy x = 42

Answer 5

a,x=39

b,x=42

Answer 6

a x +12 = 51

   x        = 51-12

   x         = 39

b) 65-x=23

        x=65-23

        x=42
