.

two divided by the difference of a number and 3 minus 4 divided by a number plus 3, equals 8 times the reciprocal of the difference of the number squared and 9.

let x=number

2 / (x-3) - 4 / (x+3) = 8 / (x^2-9) = 8 / (x+3) (x-3)

LCD: (x+3) (x-3)

2 (x+3) - 4 (x-3) = 8

2x+6-4x+12=8

-2x+18=8

-2x=-10

x=5
