from the expression: p - 1/-3 = -4, we need to solve for p.
When we have a positive number divided by a negative number the result is a negative number, that's why we can rewrite 1/-3 as -1/3, then we get:
p - (-1/3) = -4
Subtracting a negative number is equivalent to adding it, then we get:
p + 1/3 = -4
Now, if we subtract 1/3 on both sides, we get:
p + 1/3 - 1/3 = -4 - 1/3
p + 0 = -4 - 1/3
p = -4 - 1/3
To do the subtraction on the right side, we have to make sure that the numbers have the same denominator, we can do this by multiplying and dividing the 4 by 3, like this:
p = -4*3/3 - 1/3
p = -12/3 - 1/3
Now we can make the subtraction:
p = (-12- 1)/3 = -13/3
Then, the value of p is -13/3
