I think that on the board it looks more difficult than it really is. We have been taught a different way at school, personally I found easier than what was shown. I just took the question,

12a-6=5a+8

Then you take the 'A' over to the left, so the signs are on the same side. Then put the numbers on the right so you have,

12a-5a=8+6

Then its, 7a=14 so just dividing 7 into 14 meaning a=2. Im doing my gcse next year and wonder which way is best to work it out because of the test time given?

[expertmathstutor]

The way you suggest doing it is fine if you are comfortable doind it that way. Its just that way can lead to a lot of mistakes as you may try to do thing out of order. I was tought that way in school too but found the way i show it on the video makes more sense and means i can tackle more difficult problems easier.

why dont we just take away 7 to leave the A alone????

[expertmathstutor]

I'm guessing your talking about the 2nd equations. 7a means 7 times a (seven lots of a) so you can't just take 7 away to leave a alone. For example if a was 5 then 7 times 5 = 35 if you then take away 7 that'll leave 28 which is not a (which we said was 5). However if we do 7 times 5=35 than divide 35 by 7 we get 5 which is a.

Hope that makes sense, all this is covered on earlier lessons on the DVD.

Thanks
