One step equation -5 + p = -14

P = -9

To find this answer, add 5 to both sides of the equation. This cancels out the -5 on the left side while maintaining proportion to the right side. When solving this type of problem, always try to separate the variable (p) from the constants (-5 and -14).

Add 5 to both sides

p - 5 = -14

p -5 + 5 = -14 + 5

p = -9
