there is a problem in the graphing, at x=5 you have to paint a dotted line.

solve([(-4*x-8*y) = 2,(2*x) = (8+4*y)],[x,y]) [enter] returns {[7/4,-9/8]}

There is one bracket too many. {[7/4,-9/8]} => [7/4,-9/8]

It would seem to me that this is due to solve returning a set of results. To keep the type of result consistent, a singleton set is returned. (If it were otherwise, and incorporated into a larger routine, that routine would have to check the type of result returned — set or no.)

For example, solve([(y^2) = 2],[y]) returns {[sqrt(2)],[-sqrt(2)]}.

When plotting, the graphics engine does not calculate the field of view, and the viewing plane is usually empty.
An automatic adjustment is necessary.

In full screen the simulator makes a bad keyboard adjustment.

Also the virtual key press effect is not displayed very well. I suggest placing a highlighted colored frame to see which key has been pressed.

The index of a root looks like a factor since the number has a very large character, other characters could be used as superindices. ⁰¹²³⁴⁵⁶⁷⁸⁹

In the definitions it is not necessary to equal them to zero.
