The Trick or Point (as you put it) was to see if you were able to solve it... But I've since found out a lot of people on this site either use Excell or Wolframalpha. Now... Where's the point in that? Thanks for your Reply, Chester

I apologise, madah, I made an error... the Equation is : - 144 * 15.71 + y * -6.28 = (144 * y) 14.05 But hey, thanks for showing me wolframalpha.com ... What a fantastic Webb site. I'll let you work it out now...even with the help of wolframalpha.com ... if you must, lol. My...

Ok here's another way of writing it... 2262.24 + y x 15.71 = (144 + y) 14.05

Because there is another Answer. Like I said... if you say Y is -144 it means you end up multiplying both sides with Zero. There is another answer, you just have to find it. Good Luck.

BTW... γ isn't -144... Just in case you thought you could take the easy way out and multiply everything by 0 (Zero) ;)) Have fun.

Here's one to make you think... What is γ? 144 x 15.71 + γ x 15.71 = (144 + γ) 14.05

What's the Difference between Sine and arcsin? Can I still work out an arcsin problem on my calculator using the sin key?

Hi, What do I do to rearragne this Equation to make 'I' the subject... 144 x 15.71 + I x 15.71 = (144 + I) 14.05

It's all part of my Mechanical Engineering HNC, and I know a few people I'm studying with used MS Excel... but come on, using a spreadsheet isn't really showing that you can do the Math, is it. It's not getting the grey matter working. But like you said it's easier for some than it is...

But looking at your idea...it's another way... But, I get to thinking my way is a lot Simpler. (Algebra is all about reversing the equation anyway). i.e... 3x + 4 = 19 3x = 19 - 4 ...and so on. Thanks for your input

Yeah, I like your way of thinking, I 'll keep a note of that. Because up until now I didn't know it could be solved that way. Thanks For the Heads Up.

So here it is... The age of a machine, x, in years, is related to the probability of breakdown, y, by the formula... x = 3 + 1n [y / 1 - y] Determine the probability of breakdown for 1, 3 and 10 years. We start off with :- x = 3 + 1n [y / 1 - y] Using Age of machine is 1 Year x =...

Ok, so now I've got e^-2 [y / 1 - y] = -2 How do i get a value for y?

I know I'm supposed to rearrange the equation , but from there on I'm stuck... can anyone give me a hint or two?

Impossible Problem? Can anyone solve this problem... The age of a machine, x, in years, is related to the probability of breakdown, y, by the formula... x = 3 + 1n [y / 1 - y] Determine the probability of breakdown for 1, 3 and 10 years. You need to explain what you did to achieve...
