Need help rearranging formulas?
Can someone please teach me how to rearrange formulas? For example, the following formula: Pi/Ti = Pf/Tf. How would I rearrange it so that I can solve for Tf? PLEASE SHOW STEPS I NEED HELP!

--- = ----
multiple tf to the left side so it's like : (tf)(pi)/ti = pf
then muptiply the right by ti so it's : (tf)(pi) = (pf)(ti)
then divide the let by pi so it's like (tf) = (pf)(ti)/(pi)

Pi. . . Pf
---- = ----
Ti. . . Tf
Cross multiply. then solve for Tf.
PiTf = PfTi
. . . Pf Ti
Tf = --------- <==ANSWER
. . . . Pi
Io hope that helps!! :-)
