4x-9=7x+12
+9 +9
4x=7x+21
-7x -7x
-3x=21
x=-7
First, you add 9 to 12
Next, you subtract 7x to 4x
Lastly, you divide 21 by -3
Basically, you want to just get x by itself. Once you do that you will be all good. :)

First you bring the x to one side so u subtract 4x from 7x and you get the new equation as -9=3x+12 then you just solve and you get x is equal to -7
