Finf the value of x or y from given liner equation, Mathematics

Assignment Help:

41x + 53y = 135, 53x +41y =147

Ans:    41x + 53 y = 135, 53 x + 41 y = 147

Add the two equations :

Solve it, to get ... x + y = 3 -------(1) Subtract :

Solve it , to get, .... x - y = 1 --------(2)

From (1) and (2)

x + y = 3 x - y = 1

on solving , we get ... x = 2 and y = 1
