First we must distribute the 2.6 to everything inside the ()
The new equation would then be
14.3p-32.24 = 127.92
Then you would add a -32.24 to each side of the equal sign, so that the 32.34 would become a zero pair on the right side of the equal sign and cancel.
The new equation would then be
14.3p = 160.16
Then you divide each side of the = by 14.3, that way the p becomes isolated.
14.3p/14.3 = 160.16/14.3
Then you're left with
p = 11.2
Hope this helped :)
Good luck!
