7p+11=-31

To solve the equation 7p + 11 = -31, we need to isolate the variable "p".

Subtract 11 from both sides of the equation:

7p + 11 - 11 = -31 - 11

This simplifies to:

7p = -42

Now, divide both sides by 7 to solve for "p":

7p/7 = -42/7

This simplifies to:

p = -6

Therefore, the solution to the equation is p = -6.

4c+20=0

To solve the equation 4c + 20 = 0, we need to isolate the variable "c".

Subtract 20 from both sides of the equation:

4c + 20 - 20 = 0 - 20

This simplifies to:

4c = -20

Now, divide both sides by 4 to solve for "c":

4c/4 = -20/4

This simplifies to:

c = -5

Therefore, the solution to the equation is c = -5.

n/2-9+-5

The expression n/2 - 9 + (-5) simplifies as follows:

To simplify further, we can combine like terms:

n/2 - 14

Therefore, the simplified expression is n/2 - 14.

whats the anwser

The expression n/2 - 9 + (-5) simplifies to n/2 - 14.

thats wrong

Apologies for the confusion. Let's simplify the expression correctly.

Given: n/2 - 9 + (-5)

To simplify this, we need to combine like terms:
n/2 - 9 - 5

Now, let's simplify each term:
n/2 - 14

Therefore, the correct simplified expression is n/2 - 14.
