y=7/x
sub 7/x for y in first equation
7/x+x=28
times both sides by x
7+x^2=28x
minus 28x from both sides
x^2-28x+7=0
use quadratic formula
if
ax^2+bx+c=0
x=
x=
x=
sub for y
y=7/x
y=
the reciprocals are
and
times first one by
and second by 7/7
evaluate the plus and minus yourself please, my head hurts
