Need help for symbolic solving
(OP)
Hello all,
I'm new user of Mathcad Prime 9 and wondering how I can enter a symbolic solving like that :

(from Symbolic solving here : https://www.mathcad.com/en/blogs/solving-systems-e...)
I don't know how I can enter functions in brackets, the site only talk about "Symbolic Evaluation" operator, but I can't find it... how can I do ?
thanks a lot for your help

RE: Need help for symbolic solving
Next, enter each equation, one in each placeholder box in the new matrix. The = symbol is made by doing [Ctrl]-[=].
To make the arrow with solve, click Math|Symbolics in the top menu, then click on the right arrow symbol. Next, type solve,x,y,z into the placeholder box above the arrow. When you hit the Enter key on your keyboard, you will get the result. When I tried this example in Prime 5, my result was not as compact as yours (my first result was 11*a/38+7*b/38+c/38). I added the simplify keyword to the arrow but it didn't do anything.
One other thing, for consistency and good document management, I suggest using the multiplication symbol between the coefficients and the variables. In your example, only 4*x in the second row of the beginning matrix has the multiplication symbol. The implied multiplication shown for 3y, 2z, 10y, and 3z in the second and third rows works, but it's not the best practice.
