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