Homework Statement
There's a couple of questions that require the use of this, I'm having trouble with one of them, could anyone help?
Homework Equations
a) 520x - 1001y = 13
b) 520x - 1001y = -26
c) 520x - 1001y = 1
The Attempt at a Solution
The first two are easy to do,
where you set 1001 and 520 as a and b respectively.
so:
1001 = 1*520 + 481
520 = 1*481 + 39
481 = 12*39 + 13
39 = 3*13 + 0 for a)
39 = 26 + 13 for b)And you use back-substitution for the first two and change the signs accordingly, that's fine,
so you start with:
a) 13 = 481 - (12*39)
b) 26 = 39 - 13
c) 1 = ?
for c), I'm stumped. Do you use a fraction or something? or is there no solution? thanks for any help you can give me.
