eq1: 3/x+y/4=7 is linked with Input Box 1, but when I input x+y=2 in the Input Box 1, eq1 is undefined. How do i fix it?

Please add your file. Probably you missed something somewhere, so let's take a look.

my eq1 was 3/x+4/y=7 but when i input 3x+4y=7, eq1 becomes undifined.

Sorry my answer was very clear. Don't expext anyone to fix whatever problem out of a description.

You fix a car by looking at it, not by description.

thank you sir. Hope to get support in the future as well

You defined the input box as a "container" of objects of the type of your eq1, that is "implicit curves".

Any time you enter an equation that is not recognized as generating an object of the same type, the linked object becomes undefined.


A line equation can be seen as:

- a line (degenerate conic) if you enter it as y = mx + b or ax + by +c = 0 and all its variations


- a function: if you enter it as f(x) = mx + b

So basically the object you linked to your input box defines the class of equations that can effectively replace the initial one.

It looks like you can't because a linear equation is another type of object. As for an imputbox of a point you can't type an equation for a function. So you can create different files for different types of equations. I worked on your file creating some interactivity for applying the combination rule. I had to take in account that you cannot add nor multiply equations (functions you can) but you can count with LeftSide( ) and RightSide( ) experimenting with the combination rule. You can easily check and adapt what I've done.

So I first I defined eq33:Simplify(LeftSide(eq3) factor3) = Simplify(RightSide(eq3) factor3) and equally eq44. Then: Simplify(LeftSide(eq33) + LeftSide(eq44)) = Simplify(RightSide(eq33) + RightSide(eq44)) with eq33


One thing I would advise is to use larger Font Sizes

Thank you so much sir. I will surely follow your advise.
