the last two problems of my homework for community college are tripping me up and I have been working on them ALL day my brain is on overload and it just won't crunch these numbers.. Help anyone>>??

The directions are to solve by hand and show all work !

problem #1) 2e^3x-1=54

problem #2) 2log4(x^4)-3log4(3x)=3

Both the 4's I made red because on my paper they are the bases .

The e I made blue because it's the natural slanted e.
