help dnt get it

anonymous · Answer

15x  -  320     = 700 
Step one....add 320 to both sides. Now what equation do you have?

anonymous · Answer

wait do i put 320 under the 15x

anonymous · Answer

ADD..not divide..ADD 320 to both sides of the equation

anonymous · Answer

15x  -  320     = 700 
        + 320         +320

15x                 = 1020

anonymous · Answer

Now, how do I get rid of the 15?

anonymous · Answer

Divide both sides of the equation by 15
15x                 = 1020
----                   ------
15                        15

x             =   68

If you don't understand solving linear equation, you are REALLY going to be completely lost in all of your future math courses. Extremely important stuff. You will have to solve linear equations in every math course (and Physics and Chemistry and Economics etc) from heare on out. Go back and review until you get it.
