Hi,
I code R to parse data but not for solving equations. So this is
my first such problem. It is a programming puzzle.
I have these two equations.
1) 4x - 3w = 0
2) 8x - 7w =0
I know the value of x and w for
equation 1). x = 3 and w = 4
equation 2). x = 7 and w = 8
Why? Any of those equations defines a straight line, not a point. Those
two points are just one of the infinitely many solutions.
Your equations are equivalent to
eq1) w = 4/3x
eq2) w = 8/7x
the equations of straight lines passing through the origin (no
independent term).
I also know how to write more equations based on data available in the
puzzle.
How do I solve a set of such equations ? I need to find out the values of x
and w for each such equation.
There are packages to solve simultaneous equations but I've never used them.
Hope this helps,
Rui Barradas
I know that here the equations are simple because the puzzle can be
simplfied.
Thanks,
Mohan
