Answer:
x=2
Step-by-step explanation:
given 9x-12=3x we want to solve for x
To do so we need to isolate the variable using inverse operations
to get rid of the 9x we subtract each side by 9x
9x - 9x cancels out
3x - 9x =-6x
now we have
-12=-6x
now we want to get rid of the -6
to do so we divide each side by -6
-6x/-6=x
-12/-6=2
we're left with x=2
