A positive integer is 15 less than another. If 4 times the reciprocal of the smaller integer is subtracted from the reciprocal o
NemiM [27]
Translate the info given into equations:

<span>A positive integer is 15 less than another   -----> x = y - 15

</span><span>If 4 times the reciprocal of the smaller integer is subtracted from the reciprocal of the larger integer, then the result is − 3/4
</span>------> (1/y) - (4/x) = -3/4

Use substitution, replace 'x' with 'y-15' in 2nd equation

\frac{1}{y} - \frac{4}{y-15} = -\frac{3}{4} \\  \\ \frac{ (y-15)-4y}{y(y-15)}=-\frac{3}{4} \\  \\ 4(-3y-15) = -3y(y-15) \\  \\ -12y -60 = -3y^2+45y \\  \\ 3y^2-57y-60 = 0 \\  \\ y^2-19y -20 =0 \\  \\ (y-20)(y+1) = 0 \\  \\ y = 20,y=-1

We know that both x and y must be positive integers, so y =-1 is not a solution.

If y=20, then x = 20-15 = 5

Final answer:
The pair of integers is (5,20)
