error with Solve App

solve({0=F+G*4/5,0=-6000+G*3/5},{F,G}) => {[-8000.,10000.]}

An {equation list} containing the two equations, and a {variable list} containing the two unknowns, returns a {list} of the solutions.

I continue to struggle with understanding the different results when using the same equations in Home and CAS modes; this is a good example.

In CAS mode, the above equation indeed produces {[-8000 10000]}

In Home mode however, I get {[0 255]}, obviously incorrect.

I used Copy / Paste to ensure identical input.

Display mode is set to 123456.789; in Algebraic entry mode

Can someone explain? Is this due to pre-exisitng values in F and G in Home mode?
