    Let 1/x= a then , 4/x= 4a,3/x=3a Then our equations are. 4a+3y=14 and 3a-4y= 23 by substitution method we get ,a=(14-3y)/4....(1) by putting the value of 'a' on another eq. We get 3a-4y=23. ,3{(14-3y)/4}-4y=23 ,(42-9y-16y)/4=23. 42-25y=92 .25y=-92+42. Therefore, -y=-50/25. Y=2,. Again in eq. (1). a=(14-3y)/4 =(14-6)/4, a=8/4 =2 So a =2 ,y= 2.
