First of all, don't get discouraged, Elite is not meant for the mentally impaired CandyCrusher or CoD'ler, but for the strat/tac/sim/civ/traders, so it assumes you are willing to invest time and work your way into it without taking you by the hand.
You can do it. If someone with a CandyCrush/CoD background like me can understand it, anyone can do it with some time ^^
managed to find a mission it would let me accept says deliver algae to Whohler station, I am at wholer station, in the mission section all i can do is back or abandon how do i complete the mission?
This is probably a "fetch" mission, which asks you to find the described item ("algae") at another station and get it to the station where you are ("Wholer"). What you probably have to do is, fly to an agricultural world/station (Since I get the impression you skipped on the tutorials:
a) open the left sidebar by pressing "1" on your keyboard (this does NOT work when in the outfitting screen)
b) move to the tab "Navigation" if you aren't already in it with the buttons "Q" and "E"
c) Select "System map" if you think there are multiple stations in the star system you are in, or "Galaxy map" if you know there isn't.
d) Find a planet that looks like Earth. It's usually agricultural
Regarding missions, before taking on a "Transport the stuff we are giving you to station X" mission, check if you can really reach the system given. At the start there might be some systems too far away for you and you need a bigger Frame Shift Drive to fly farther.
Also, trading is REALLY easy if you read the Galaxy/System map right. The stations at the start are always described as either industrial, agricultural, refinery, extraction or hightech.
Buy one 4 tons of something that is in high supply and way below galactic average.
Use your common sense (or read the description of the items in the commodities tab, they usually drop a hint in like "...is used to refine ore..", "..is the processed in industrial.." etc.) and find a station that probabyl needs your stuff.
If your common sense and/or reading skills aren't up to par, google for the elite dangerous trading bible, which is an image showing you what you need.
If you have no idea, you can click on the "Galactic average" header, and in the drop down menu, find a system close to you. It will show you "export to", "import to". While this may be deceiving, it is usually a good hint where you can sell stuff (hint: it's where goods are exported to).
Hope this helps.
Good luck, Commander.
