p=-4p=4

Explanation:

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

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

15p-4p-20=-6415p4p20=64

11p-20=-6411p20=64

"add 20 to both sides"add 20 to both sides

11p=-64+20=-4411p=64+20=44

"divide both sides by 11"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
