I hope this question is in the correct section. There's this problem I'm looking at in Applied Maths (Traditionally I've been really bad at maths, I have neglected it for a long time)
On one line it says
1/2 (5v/6) v = 375
The next line it becomes
5/12v^2 = 375
I've just no idea what happened at all, really. I've tried to look this up online but I guess it's just a very specific example, I went over to https://www.mathway.com/ and that did not help.
My guess is that everything on the left side of the equation gets multiplied by 2, so as to remove the half, increase the 5v/6 to 5/12 and then v becomes v^2.
Actually that makes no sense.
Help ? Thanks in advance.
Actually, I'm teaching myself maths atm I guess (If I could be as bold to call it that) I was wondering what members think of Khan Academy's Algebra videos ? I'm thinking of doing them.
