#p=-4#

Explanation:

#"to solve the equation collect terms in p on the left"#
#"side of the equation and numeric values on the right side"#

#"subtract "4p" from both sides"#

#15p-4p-20=-64#

#11p-20=-64#

#"add 20 to both sides"#

#11p=-64+20=-44#

#"divide both sides by 11"#

#(cancel(11) p)/cancel(11)=(-44)/11rArrp=-4#

Isolate the variable.

Explanation:

Put the coefficients on one side of the equal sign and the constants on the other side (subtract #15p# on both sides and add #64# on both sides).

You will get

#-11p=44. #

Divide by #-11# on both sides then you will get the solution:

#p=-4#
