This should be really easy but I've been trying to some of my A-Level homework and I can't get my head around it.
6root7 - 2x = 5 + (3root7)x
there's more than one way I can seperate the x's, and each way seems to give me different solutions.
I can do:
6root7 - 5 = (3root7)x + 2x
-2x - (3root7)x = 5 - 6root7
- (3root7)x - 2x = 5 - 6root7
Is there a special way to do this, am I missing a way to order where each number is placed to make sure I get the right answer?
Should be such as easy question, especially for an A-Level student but a couple of questions like this are catching me out.
Any help would be greatly appreciated.
