दि3x+2y=62x-3y=—4# – InterviewSolution

1.

दि3x+2y=62x-3y=—4#

Answer»

3x + 2y = 6.......(1)2x - 3y = 17..... (2)

Multiply eq(1) by 3 and eq(2) by 2, add eq(1) and eq(2)

We get,9x + 6y = 184x - 6y = 34

13x = 52x = 52/13 = 4

Put x = 4 in eq(1)3*4 +2y = 612 + 2y = 62y = - 6y = - 6/2 = - 3

Value of x = 4, y = - 3

thanks
