solve linear equ, using octave-forge

[Fred J.]

I have tried to sove these simple linear
one/more-than-one variable linear function using other
tools but no ssuccess, I am wondering if they can be
done with octave-forge algebra functions, thanks for
your help

solve for x:
2 / (x + 2) = -(x / (x^2 + 5 x + 6))

solve for r:
solve(v = m(1 / b - 5 ar / m), r)

regards
