I got x=1 but I don't think that's right..

anonymous · Answer

It's not, try to check it again.

anonymous · Answer

I got 5^3x = 5^2x=1
then I did: 3x=2x+1
then I got x=1 
:(

anonymous · Answer

2(x+1) is not equal to 2x +1 ..

anonymous · Answer

Oh I see lol I know the answer. You would want to use logarithms

anonymous · Answer

$$\eqalign{
&5^{3x}=25^{x+1} \
&5^{3x}=(5^2)^{x+1}\
&5^{3x}=5^{2x+2} \
&3x=2x+2 \
&x=2
}$$

The you just gave the answer though...He had the right method up until the point and you corrected him...That's all...Besides. the fourth step was the issue and I skipped the simplifying of that. There is not really any answer giving away.
