I am assuming you mean and not . We are given:

I would rewrite this as:

so that we may use the property to then rewrite the equation as:

Next, divide through by 3:

Next, use the fact that to write:

To finish now, on the right use the property , then equate the resulting arguments, then solve for . - Dec 9th 2012, 02:02 PMbjhopperRe: Help me tO solve this algebra..please
another method

3ln(2x) =3 +ln(27)

ln (2x/3)^3 =3

e^3 =(2x/3)^3

e = 2x/3

e = 2.303
