#p=5#

#3+p=8#

Subtract 3 from both sides

#3+p-3=8-3#

#p=5#

#p=5#

We want to solve for #p#, and right now #3# is being added to it, so we must do the inverse of adding #3#, which is subtracting #3#.

It is very important to realize that we must do this to both sides to maintain the equality. We get

#p=8-3=5#

Therefore, #p=5#.

Hope this helps!
