Answer 1

Answer:

Given pair of linear equations is 2x + 5y = 1 …(i) And 2x + 3y = 3 …(ii) On subtracting Eq. (ii) from Eq. (i), we get 2x + 3y – 2x – 5y = 3 – 1 ⇒ – 2y = 2 ⇒ y = – 1 On putting y = – 1 in Eq. (ii), we get 2x + 3( – 1) = 3 ⇒ 2x – 3 = 3 ⇒ 2x = 6 ⇒ x = 6/2 ⇒ x = 3 Hence, x = 3 and y = – 1 , which is the required solution.Read more on Sarthaks.com - https://www.sarthaks.com/923860/solve-the-following-system-of-equations-by-elimination-method-2x-5y-1-2x-3y-3
