60x+80y=1--->eqn 1

4[13x+24y=1/4]

52x+96y=1

36[60x+80y=1]

30[52x+96y=1]

5[12x+16y=1/5]

60x+80y=1--->eqn 1

4[13x+24y=1/4]

52x+96y=1--->eqn 2

[60x+80y=1]36

[52x+96y=1]30

2160x+2880y=36

-1560x+2880y=30

600x=6

x=1/100

substitute the value of x in any equation

e.g

60(1/100)+80y=1

80y=1-6/10

y=1/200
