Question

solve D=abc for b

Answer 1

This looks worse than it is... it's just a matter of getting "b" all alone on one side of the equation.

Answer 2

d/ac

Answer 3

just like if you had 2x = 4, to solve for x, you would divide both sides by 2 to get x all alone...

Here, you want to get "b" all alone... so divide by all the stuff surrounding the "b" term.

Answer 4

jake is right I would rather you teach it to me and show how to get to the solution so I understand how to do it next time

Answer 5

ok so it would look like d/b ac/b right

Answer 6

sorry @vortish

Answer 7

I'm not sure I followed you last comment @vortish

Solve D=abc for b:

Get b all alone... what do you need to divide the right side by to get "b" all alone?

Answer 8

You divide both sides by the stuff next to the "b", right? Divide both sides by "ac".

Do you follow?

Answer 9

i think so so you are saying that it would db/ac b/ac and the bs would cancel each other out to leave us with d/ac

Answer 10

yes, sorry, if that's what you said before, that's correct... I just didn't follow it.

you have D on the left, and abc on the right... divide both sides by "ac" and the "ac" cancels on the right leaving "b"... and on the left, you just have D/ac

It's just moving terms around... "solving for" just means getting whatever you're solving for all alone by whatever you have to do.

Answer 11

k thanks jake your a good tutor

Answer 12

trying... just like you.
