WebThe congruence we write in the equivalent way: 7 x – 5 y = 3. The one particular solution to the equation above is $x_0 = 2, y_0 = -3$, so $7x_0 – 5y_0 = 3$ is valid. By subtracting the obtained equations we obtain 7 ( x – x 0) – 5 ( y – y 0) = 0. It follows x – x 0 = 5 t 1, k 1 ∈ Z, that is, x = 2 + 5 k 1, k 1 ∈ Z. irb limited reviewWebAdvanced Math questions and answers.
