Nettet7. jul. 2024 · There are infinitely many integer solutions for the equation 4x + 6y = 8 because (4, 6) = 2 ∣ 8. We use the Euclidean algorithm to determine m and n where 4m + 6n = 2. It turns out that 4( − 1) + 6(1) = 2. And also 8 = 2.4. Thus x0 = 4.( − 1) = − 4 and y0 = 4.1 = 4 is a particular solution. chennai shoppersNettetA Diophantine equation is a polynomial equation in two or more unknowns for which only the integer solutions are sought (an integer solution is a solution such that all the unknowns take integer values).
