Answer:

p = 20

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtraction

~

Isolate the variable, p, by multiplying 4 to both sides of the equation:

[tex]5 = \frac{p}{4}\\ 5 (* 4) = \frac{p}{4} (* 4)\\ 5 * 4 = p\\p = 20[/tex]

p = 20 is your answer.

~
5 = p/4

You have to put unknowns (p) on 1 side and knowns on other side.

To get p alone you have to move the 4. Since p divides 4, you have to multiple by 4 to cancel it out. BUT Remember if you have to change one side, you have to change other side by same amount too, so the equality stays true. So multiply BOTH sides by 4

4* 5 = (p/4)*4

the 4s on the right side cancel each other because 4/4=1
So,

20 = p
