Solve the equation ax + bx = 1
where 0 < a, b < 1 and a + b < 1, in the special cases:
(i) a = b (ii) a = 1/2, b=1/4
You can find exact solutions to the equation ax + bx = 1
in special cases like (i) and (ii).
More generally you will need to use a numerical method for
finding approximate solutions. See
Equation Attack.
