Answer 1

Step-by-step explanation:

15x + 17y = 21. . . (I) 17x + 15y = 11 . . . (II) In the two equations above, the coefficients of x and y are interchanged. While solving such equations we get two simple equations by adding and subtracting the given equations. After solving these equations, we can easily find the solution. Let’s add the two given equations. Read more on Sarthaks.com - https://www.sarthaks.com/368659/solve-the-following-simultaneous-equations-15x-17y-21-17x-15y-11
