Question 8548
First, you must get all the x terms on one side.  To get rid of the 6x on the right side, you can add -6x to each side:


15x - 4 = 6x + 3
15x -6x - 4 = 6x - 6x + 3
9x - 4 = 3


Next, you need to get all the "non-x" terms on the OTHER side.  In this case, it will be nice to get rid of the -4, so you add +4 to each side:
9x - 4 = 3
9x -4 +4 = 3 + 4
9x = 7


The last step is to get the x by itself.  To get rid of the 9, you must realize that the operation between the 9 and the x is multiplication, so you must undo multiplication--that is, divide both sides by 9.


{{{ (9x)/9= 7/9}}}

{{{x = 7/9}}}


It's ugly, but in math you just have to get used to ugly!!  It happens all the time.  Life doesn't always come out even!!
