Hello akshay! Welcome to PF!
The forum rules says that the OP needs to show his/her attempt before asking for help on the problem.
Did you try to apply KCL or KVL? There is even a shorter method too to solve this problem.

ive tried applying it but can't seem to understand how to get the voltage across the 2k and 5k resistors please help!.Im begging.

i think u take the node at the top and maybe the top equals vo
so at the node so you have (vo-30)/2k+(vo-20)/5k+vo/4k
or something like that, I am not really sure I am a first year engineering student too :)
