    we want to find a and b in terms of constants only.

  36. Inopeki

    So whats a constant?

    constant is something which value is fixed.

  39. Inopeki

    Ok, so we can subtract a from both sides to get b on the top one, right?

    Why don't we add the equations? like this \[ a+b+a-b=9+11\]

    Ok. Here's the solution ax - a = x - 1 ax - x - a = -1 ax - x = a - 1 x(a - 1) = a - 1 hence x = 1
