Hey guys, I'm stuck at this last question of my online math test, i'm free to use help. You have to write it as simple as possible and one of the following 4 awnsers is correct. I've been struggling with this for a while now and can't seem to figure out the right working order. I tried putting all den. to 6 first then solve the the x and y's but I can't get the square root 6 away on the bottom, or my awnser is nowhere near any of these 4 . Any help with working order appreciated! thanks
