Question

solve the following simultaneous equations using cramer's ryle :
y = 2x + 14 ; 7x = 2y + 5 ​

Answer 1

2x – y = 17 3x + 5y = 6 ∵ ∆ ≠ 0, ∆1 ≠ 0 and ∆2 ≠ 0 ∴ Solution will be unique. By using Cramer’s rule Hence, solution is x = 7, y = -3 (ii) Given, 3x + ay = 4 2a + ay = 2, a ≠ 0Read more on Sarthaks.com - https://www.sarthaks.com/707731/use-cramers-rule-to-solve-the-following-system-of-equations-i-2x-y-17-3x-5y-6
