Answer:
im guessing 53p
Step-by-step explanation:
i dont know that much about theses though so sorry
law's of exponents
e^(x-5)*e^(3x+8) = 19
e^(x-5+3x+8) = 19
e^(4x+3) = 19
take the natural log, which is base "e" of both sides.
ln[e^(4x+3)] = ln[19]
4x +3 = ln[19]
4x = ln[19] - 3
x = (ln[19] - 3) / 4
x = -0.0139

All you have to do is subtract 85 from 510 till you have 0
