12x + 16y=1/5 & 13x + 24y =1/4,find value of x & y.

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=16/10
y=1/200
