Let to be 1/x=a
Let to be 1/y=b

then,

2a+5b=1*60
60a+40b=19*2



120a+300b=60
120a+80b=38

_______________
220b=22
b=22/220
b=1/10

then,

putting the value of b in another equation,,

60a+40*10=19
60a+4=19
60a=19-4
60a=15
a=15/60
a=1/4



then,


1/x=1/4
x=4



Again,
1/y=1/10
y=10



that's all
