could somebody help me with this?

First step in completing the first problem (3x+9=18) is to subtract 9 from both sides of the equation
This leaves us with 3x=9
The next step is to divide both sides by 3 to get the x by itself
This gives us x=3 which is the solution to the problem!
Hope this helps! Let me know if you get stuck on a problem or need clarification.
