solve the linear equation 2x-6y=12or5x+8y=12 – InterviewSolution

1.

solve the linear equation 2x-6y=12or5x+8y=12

Answer»

2x - 6y = 12..... (1)5x + 8y = 12....(2)

Multiply eq(1) by 5 and eq(2) by 210x - 30y = 6010x + 16y = 24

Subtract these equations-46y = 36y = - 18/23

Put value of y in eq(1)2x - 6*(-18)/23 = 12x = 6 - 54/23x = 138-54/23 = 84/23
