Prime7 Symbolic calculation issue.

I am using Mathcad Prime 7.0 7.0.0.0

Prime3 could solve below two parallel equation (Placed in Vector form). Symbolic calculation worked as below.

[120 = x * (1*10^6)^y]

[30 = x * (1*10^3)^y] -->Solve,x,y,float -->[7.5 0.20068666]

If I do the same in Prime7, It resulted "No solution was found".

Solving block works as expected. Is there a way to solve this in Symbolic calculation in Prime7?

The symbolic engine in Prime 3 is MuPad, the symbolic engine in Prime 6 is a new symbolic engine by default, but you can choose to use the legacy engine (MuPad). In Prime 7 you only have the new symbolic engine, the choice for legacy symbolic engine is gone. It will probably take some time (and iterations of Prime versions) before the new symbolic engine can do all the tricks that MuPad can.

Until then, use numeric solutions (in a solve block), or keep using Prime 3, or 6...

Success!

Why (since you're searching for numeric values) would you try to use symbolic math?
