To solve for p, set up the equation
5p + 9 = p - 3
5p = p - 12
4p = -12
p = -3
to prove the answer, substitute -3 for p and prove
5(-3) + 9 = (-3) -3
-15 + 9 = -6
-6 = -6
Negative times positive equals negative.
Your question does not make sense. It would probably be interpreted as a + = ++a ---a
A minus plus a minus is not necessarily positive. A minus multiplied by a minus is. The reason being that the minus of a minus is a positive. It's a double negative.

negative 49. This is because a minus multiplied by a plus is a minus.
Negative times positive equals negative.
n=45
5. Just do 9 minus 4. 5 plus 4 equals 9
It is an equation and the value of n is 9

It depends if 1 plus tan theta is divided or multiplied by 1 minus tan theta.
That will depend on the plus or minus value of 12 which has not been given.
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
