Were learning how to calculate “Mean Arterial Pressure”. the equation is:

MAP=diastolic blood pressure + 1/3( pulse pressure) or just

MAP=DBP+ 1/3(PP)

If the MAP is 93 and the systolic BP is120. How would I calculate diastolic blood pressure and pulse pressure?

please show all steps im really confused. Thank you for your help.
