You can use grep to do this, on Windows and Linux.  It is not limited to "Maple" doc's

Without looking at your system, it is hard to say.  Take a look here for a meaning, and a possible solution.

Alec's suggestion is the preffered method.  But, your statement about linsolve in Maple 14 not working is not accurate.  The example below is done with Maple 15.  It works in v14 as well.

From the help pages:

Important: The linalg package has been deprecated. Use the superseding packages, LinearAlgebra and VectorCalculus, instead.
- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.

I might be understanding the question differently than Doug.  I see "y" being fixed, and all "x's" that satify this fixed value of "y" being solved for.  If this is the case, then ?solve needs to be used.  Otherwise, use Doug's method above.  In the example below, "y" is chosen with values that vary from 1 to 3, and all "x's" solved that satisfy the given value of "y".  If only 1 value of "y" is needed, then ?seq can be dropped. This is my interpretation of the question.

Try the ?collect command, and see if it works for your equations.

See link here.  You can cut and past it into a new worksheet to see what it does.  As stated in the link, this is not a very good method.  See article here.  Axel's approach above would be a better way to do this, especially if the data source adds an element of noise.

The problem seems to be with the "filled" option, in the plottools command for the ellipse.

As a potential workaround, change:

sit := seq(ellipse([-1.8+(1/10)*t, 1.9], .4, .1, filled = true, color = black), t = 0 .. 100):

to

sit := seq(ellipse([-1.8+(1/10)*t, 1.9], .4, .1, color = black, thickness = 5), t = 0 .. 100):

and see if the animated plot is acceptable to you.

This will also work for your Little test, just change it to:

display([arc2, siege]);

Try using square brackets in your display command, and see if that gets you there.  It seems to work for the attached.

Try rewriting your equations like this.  Avoid using square brackets to express your equations.

restart:
solve({gama2*q2 - 2*gama1*XA=0,-q1 + 1 - 2*q1- C=0, -q2 + 1 - 2*q2 - C + gama2*XA=0},{gama1,gama2,C});

The exponential function, exp(x), calculates the value of e to the power of x, where e is the base of the natural logarithm, 2.718281828... .

See the help page, and take a look at the first example.  ?geom3d[sphere]
Use

point(A,- 8, 3, 11), point(B,5, - 7, 1), point(C,- 15, 4, - 6),point(Dd,10, 2, 9);

for your points

and

sphere(s, [A, B, C,Dd]);

to get the equation.  The rest of what you need is in the help page.

The last point was changed to Dd, instead of D, because D is proteceted in Maple.

Try this and see what happens.  If you are still having trouble, upload your worksheet, or cut and

paste what you have tried that is giving you trouble.

Start by browsing existing worksheets in the Application Center.  Download them, execute them, study them, make changes, re-execute to see what happens. 

One such worksheet is here.

Download and execute the following worksheet.  You can execute it by clicking on the 3 !!! marks on the top toolbar.  The examples are similar to yours.  One more thing.  In Maple, The number Pi is represented by Pi (not pi).
