WebThere are three main methods to solving system of equations, they are: Substitution Method Elimination Method Graphical Method Web12 = 2 a + b ( mod 26) 15 = 9 a + b ( mod 26) Subtracting the first from the second gives. 3 = 7 a ( mod 26) Using the Euclidean Algorithm, we get that 15 × 7 = 105 ≡ 1 ( mod 26). So, multiplying both sides by 15 we get. 19 = a ( mod 26) Subtracting 2 times the second from 9 times the first yields.
