**5+x=10

\(\Rightarrow x=10-5\)

\(\Rightarrow x=5\)

Vậy x=5

**9+x=12

\(\Rightarrow x=12-9\)

\(\Rightarrow x=3\)

Vậy x=3

**18:x=6

\(\Rightarrow x=18:6\)

\(\Rightarrow x=3\)

Vậy x=3

Answer 2

[•ℳเйʑ❤๓ê❤ǥą๓ë⁀ᶜᵘᵗᵉ]

5 + x = 10

       x = 10 - 5 

       x = 5 

9 + x = 12 

       x = 12 - 9

       x = 3 

18 : x = 6 

        x = 18 : 6 

        x = 3
