you have to do 6+12 which equals 18
x=18
so it will be 18-6=12
your welcome :)
Answer:
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) )
