Question

solve for x: e^(x-7)/(e^-7)=28

Answer 1

e^(x-7+7)=28
e^x=28
x=ln 28
x=3.33(2 decimal places)

Answer 2

wait im confused about the signs of the 7s. wouldnt the denominator come up and equal to e^(x-7-7)?

Answer 3

no because you had a \(-7\) in the denominator, so when it comes up it turns in to \(--7=7\)

Answer 4

oh ok i wrote it wrong from the start ha. thank you very much
