Answer:
Prime= 37, 71 Composite= 65, 82
Step-by-step explanation:
Prime numbers can only be divided by 1 and itself and composite numbers can be divided by more.
Let x represent the larger number.
1/(x -28) +4/x = 1/6
Multiplying by the product of denominators, we have
6x +24(x -28) = x(x -28)
In standard form, this is
x^2 -58x +672 = 0
(x -42)(x -16) = 0
The two numbers are (-12 and 16) or (14 and 42).
