solving equations

[venkat0249]

Is it possible to solve equations using hypernext? If not can we solve using Rb script?
 For example: x+y=10, x+2y=13 then find x and y values.
answer : x=7 and y=3

Yes you can use either but of course RBscript is much faster that HyperNext but HyperNext script is much easier to use

Here is a link with an algorithm:-

Thank you for the answer. Unfortunately the link is not working  can you give me any other link?

Their site is very slow to respond.

Here is the HyperNext based on their text - it gives the same answer for their problem.
Sorry I don't have time to tidy it up etc but their page should clarify it.
The script goes into a button and the answers for x and y appear in fields 1 and 2 respectively.

Code: [Select]

Local a,b,c,d,e,f,x,y
Local t1,t2,t3,t4

@'ax+by=c equation format will be like this
@'dx+ey=f

@x = (c * e - b * f) / (a * e - b * d)
@y = (a * f - c * d) / (a * e - b * d)

Put 1 into a
Put 1 into b
Put 3 into c
Put 2 into d
Put 3 into e
Put 8 into f

@ calc c
@x = (c * e - b * f) / (a * e - b * d)
Put c into  t1
Multiply t1 by e
Put b into t2
Multiply t2 by f
Subtract t2 from t1

Put a into t3
Multiply t3 by e
Put b into t4
Multiply t4 by d
Subtract t4 from t3

Put t1 into x
Divide x by t3

@ calc y
@y = (a * f - c * d) / (a * e - b * d)
Put a into t1
Multiply t1 by f
Put c into t2
Multiply t2 by d
Subtract t2 from t1

Put a into t3
Multiply t3 by e
Put b into t4
Multiply t4 by d
Subtract t4 from t3

Put t1 into y
Divide y by t3

Put x into field 1
Put y into field 2

Thank you soooo much....
