i am lost on what to do with these two questions:

they are more intense than other ones we have even looked at in class

solve for x:

8^6x-6 = (1/16)^8x-2

x ='s ___ ??

and another similar one:

2^2x+9 =3^x-44

x='s ___ in terms of logarithms or to four decimal places.

any guidance would be great!
