hey bro/gal :sleeping:
let 1/x be u and 1/y be v.
=) u/5 + v/6 = 12
=) 6u + 5v/30 = 12
=) 6u + 5v = 360 - - eq3.
by eq 2:
=) u/3 - 3v/7 = 8
=) 7u - 9v /21 = 8
=) 7u - 9v = 168 - - eq4.
multiply eq3 by 7 & eq4 by 6.
=) 42u + 35v = 2520 - - eq5.
&
=) 42u - 54v = 1008 - - eq6.
Subtract both :
=) 35v - (-54v) = 2520-1008
=) 89v = 1512
=) v = 1512/89
Put value of v in eq3:
=) 6u + 5(1512/89) = 360
=) 6u = 360 - 7560/89
=) 6u = 24,480
=) 89u = 4080
=) u = 4080/89
Hence x = 89/4080 and y = 89/1512.
let 1/x be u and 1/y be v.
=) u/5 + v/6 = 12
=) 6u + 5v/30 = 12
=) 6u + 5v = 360 - - eq3.
by eq 2:
=) u/3 - 3v/7 = 8
=) 7u - 9v /21 = 8
=) 7u - 9v = 168 - - eq4.
multiply eq3 by 7 & eq4 by 6.
=) 42u + 35v = 2520 - - eq5.

=) 42u - 54v = 1008 - - eq6.
Subtract both :

=) 6u = 360 - 7560/89
=) 6u = 24,480
=) 89u = 4080
=) u = 4080/89
Hence x = 89/4080 and y = 89/1512.
