VERY EASY, WILL GIVE 50 POINTS FOR CORRECT ANSWER ASAP AND WILL GIVE BRAINLIEST.

you have to do 6+12 which equals 18

x=18

so it will be 18-6=12

your welcome :)

x = 18

Step-by-step explanation:

So just substitute the value of y in the equation.

x - y = 12

x - 6 = 12

Then solve for x:

x - 6 = 12

  +6    + 6

x = 18

So the solution would be x = 18.

(If you want it in a coordinate then (18, 6) )
