Re: Algebra -Subject
It does take experience to do some of these. You gain that experience by doing them. The beginning stuff is right here:
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Algebra -Subject
How about this one here:
Can you get c as the subject?

Re: Algebra -Subject
That is correct!
Make b the subject.

Re: Algebra -Subject
Just a question, If I distribute the b on the right, I must also distribute it for 2 ? (Must I distribute to all the right side of the equation ?
1/a=2b ?

Re: Algebra -Subject
Im trying to isolate b on the right of the equation, but must I also distribute the B to the whole right side of the equation ?
*b 1/a=1/b+2 *b (to the 1/b AND to the 2)
which gives :
b/a=2b
?

Re: Algebra -Subject
The left side is correct.
When you multiply the right side by b, that means everything on the right gets multiplied by b. Try it again.

You only need some practice on that type.
