Let

a-------> one of the numbers

b------> the other number

we know that

[tex]a+b=x[/tex] ----> equation A

[tex]a=12[/tex]

substitute the value of a in the equation A

[tex]12+b=x[/tex]

solve for b

Subtract [tex]12[/tex] from both sides

[tex]12+b-12=x-12[/tex]

[tex]b=x-12[/tex]

therefore

the answer is

The other number is [tex]x-12[/tex]
