The general solutions for (i) and (ii) are
In both cases substitute
and you'll find A and B by means of a 2 x 2 system.
the question is
''Find the solution to the equations.
(i)
(ii)
for i) i have got
If , so
general solution:
therefore actual solution is
for ii) i have got
If
,
so
general solution:
where A,B are constants.
after using
,
I've got A=125
I'm wondering is my general solution incorrect and how can I find the constant B?
