X=6y
sum of their reciprocals
(1/x)+(1/y)=7
x=6y
1/6y+1/y=7
1/6y+6/6y=7
7/6y=7
times both sides by 6y
7=42y
divide both sides by 42
1/6=y
x=6y
x=6(1/6)
x=6/6
x=1
the numbers are 1 and 1/6

Step-by-step explanation:
f(x) =
g(x) = 2x + 3
(x) = 'f' divided by 'g'
Substitute.
x cannot be -
because that would create a zero in the denominator.
That's a no-no.
It makes it 'undefined'
