## vortish 2 years ago solve D=abc for b

1. JakeV8

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

d/ac

3. JakeV8

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.

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

5. vortish

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

6. sabika13

sorry @vortish

7. JakeV8

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?

8. JakeV8

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

9. vortish

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

10. JakeV8

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.

k thanks jake your a good tutor

12. JakeV8

trying... just like you.
