(d+7)/(d2-49)(d+7)/(d+7)(d-7)1/(d-7)
D- -7 is the same as D+7 because - -7 = +7
(-1)*(-15) = +15 so -15 = + 15/(-1) So 15/(d-7) - 15/(7-d) = 15/(d-7) + 15/[(-1)*(7-d)] = 15/(d-7) +15/[-7+d] = 15/(d-7) + 15/(d-7) = 30/(d-7)

If you are seeking d more than 7, you'll need to add d to 7. We find that d + 7 is d more than 7. In this case, d is a variable, but the math is direct and correct.
