Using the Euclidean Algorithm to solve 13 in Z30 30 = 2x13+4 13= 3x4+1 Eliminating multiples of four 1= 13-3x4 = 13-3(30-2x13) = 7x13-3x30 ---- How was this achieved? Thanks

Could you explain what is going on here? I don't understand why we do it in that way. My maths books just tells me how and not why. Thanks.
