    Quick algebra question

    In a line:
    u=nv+nln(theta)
    (y=mx+b, n and theta are constants, v=x, u=y)

    u = -3.89
    v = 0

    or

    u=-1.9
    v=0.693

    How can I isolate and find either n or theta?

    Just write it out

    -3.89 = n \cdot 0 + n \ln \theta
    -3.89 = {\color{blue}n \ln \theta}

    -1.9 = 0.693 n + {\color{blue}n\ln \theta}
