So there are these questions I couldn't get. It's taking me a while now so I figured I might need some expertee help. I'll post the tri-equations but I hope you people can take me through it step by step and what ways did you use to solve it.
So here we go!
xy/(x+y) = 1/2 yz/(y+z) = 1/3 and xz/(x+z) = 1/7.
Thanks for your patience, time and help !
By flipping the fractions over on each side and then splitting the left side into partial fraction, you can simplify each equation down to:
1/x + 1/y = 2
1/y + 1/z = 3
1/x + 1/z = 7
Hopefully that should be a much easier set of equations to solve. Post again if you still don't get it.
Why did the vector cross the road?
It wanted to be normal.
obviously, the second set of values doesnt work, but the first set does.
so, the answer is
did you understand how i did it?
basicly, for the first equation, i rearranged it for the second variable being the subject
then in the second equation, i substituted the rearrange first equation, and then got another rearrange equation for the third variable
then substituting into the last equation, i got a value for x, which i plug into the 2 rearranged equations, for a value for y and z
