algebra question? look at pic!

Answer 1

I first got 4.5 but that wasn't right. please help!

Answer 2

use this identity->\[x^a \times x^b=x^{a+b}\]

and remember when bases are same powers are equal-\[x^a=x^z\]then a=z
now do it

Answer 3

e^(3x-4)=(e^3x)*e^(-4)
(e^-x)*(e^3x)*e^(-4)=(e^2x)*e^(-4)=5e

272.99075015e=e^2x
5.609437912*1=2x
x=2.8047

Answer 4

Thanks!
