In Todays blog, I will be explaining how to solve 2x-7=15. The first step is to isolate the variable By that I mean to add 7 into 15. This would add up to 22. If you are asking why you have to add, well this is because if the sign right next to the variable is positive than you subtract, however if it is negative than you add. Once the first step is done all you have left is 2x=22. From this point, it is really easy. All you need to do is divide 2 by 22. The answer is 11. The same thing goes with the +/- deal. If the sign is multiplication then you divide and the other way around. This is simply all you have to do for a problem like this one.
I hope that you have learned a lot about my blog, and that you will refer back to this when you have a problem like this. Just remember that multiplication and division rule. It is fairly simple if you show your work and follow these steps. If you do not know or forget which step to do first follow the GEMS rule. GEMS stands for grouping exponents multiplication/division, and subtraction/addition. This is what we learned awhile back in 5th grade, so this should be easy.
