Step One: When dealing with equations you must do the opisit operation. For this equation we are addinf so we need to sub tract.
What you do on one side of the equal sign you must do to the other.
Step two: we subtract nine on both sides. The two nines cancel each other out. Now we subtract 9 from 14 which gives us X.
To see if this is corect we can plug 5 in place of "x" and so our problem is 5+9=14 if it dose you know you did the problem right!
