Answer:
x=6
Explanation:
Hello There!
Our whole objective is to isolate the variable (x) by using inverse operations
2x-3=9
to get rid of the -3 we add 3
Remember whatever we do to one side we have to do to the other side so we add 3 to each side
-3+3 cancels out
9+3=12
now we have
12=2x
now to get rid of the 2 we divide by 2
so we divide each side by 2
2x/2=x
12/2=6
we´re left with
x=6
