Trying to find the correlation for 2 variable when controlling for 2 other variables

#1
I summed up some of the info we are already provided:

N=50

Having job and exam performance--- r= -.3
Having job and and Studying--- r= -.4
Studying and exam scores--- r= .70

We are suppose to calculate the correlation between having a job and exam scores while controlling for the effects of studying on exam scores.

Not necessarily asking for anyone to solve this problem, but if you could somewhat start me off in the right direction that would help SO much!! I am slightly lost. This was just a practice question we were provided and unable to go over in class, and we have an exam this week! Would this be considered a partial correlation? Also, we are provided with the Fishers r to z table if needed.

Thank you again so much!!
