Write subject formula

[Music] hey guys today I'm going to show you how to change the subject of a formula now it sounds a bit confusing changing the subject but all it means is they're going to be rearranging equations to get one of the letters by themself and in these ones were making X the subject so it means we need to rearrange the equations to get x equals so there are things that's not x will be on the other side of the equal sign so let's look at the first one here's that x value remember this is what we need to get by itself and it's very similar to solve the equation if you know how to solve linear equations these should be quite easy it's exactly the same method if certainly don't you need to calculate anything you just rearranging the equation so when we're rearranging this to get X by itself we leave whatever is closest to X together for the moment so we get rid of this part first and the opposite of - to do is to + and remember if you cannot be on the left hand side of equals you have to do the same on the right hand side to keep the equation balanced so on the next hand side minus B plus B that's a zero so whenever you do the opposite which is cancel each other out and somewhere left with one X Y on the right hand side T plus B well we can't actually work that out because they're different letters so we just leave it as that C plus C so now the last step at a moment X B multiplied by Y so the opposite of multiplying by Y is two divided by Y and remember to do the same thing on both sides of the equation on the left hand side where you do the opposite they just cancel because Y divided by Y is 1 so elected One X and on the right hand side just be careful because you need to divide all of this by Y so the best way to write this is to write as a fraction because if we put C plus B or the top of Y underneath that means we're dividing all of that numerator by Y so that first one we've made X of subjects or / formula because it says x equals okay on to number two so this point is a bit different because we've got a fraction well remember I said leave whatever closest to X to the moment so we're going to be get written get getting rid of this plus end so we need to subtract N and remember to do the same thing on both sides on the left hand side remember it is cancel because that goes to 0 so we're left with x over T and on the right hand side well V - Becca just be Madison...
