How to convert multivariable functions of two independent variables to functions of one independent variable?

3x+x+1=5-x

LE(x,y)=3x+x+1

f(x)=3x+x+1

RE(x,y)=5-x

g(x)=5-x

You need to use CAS, since GeoGebra simplifies equations automatically.

Open CAS View, type in 3x + x + 1= 5 - x in row 1, and select the Keep Input tool before pressing Enter.

In row 2, define f(x):=LeftSide($1)

In row 3, define g(x);=RightSide($1)

Using $ gives you a dynamic reference to row 1, such that when you modify the equation contained in it, also f(x) and g(x) change accordingly https://wiki.geogebra.org/e...

I am using the algebra view from inputbox. I am not using cas view.

You need CAS for this :) because GeoGebra locks the input without automatically simplifying it.
