For these types of equations you are solving for a variable, so to solve for the variable you must see what is happening to it and and do the oppsite, for example:

1) p - 10 = -33

answer: p= -23

the variable p was being subtracted by 10, now you must do the opposite, so add 10 to both sides of the equation, that gets your answer of -23

2) - 60 = -3f

answer: f= -20

Whats happening to the variable on this one? It is being multiplyed by -3, so do the opposite, divide both sides by -3, this gives you f=20, it should be positive though, a negative divided by a negative equals a positive.

See if you can do the rest.
