To find the value of p, isolate/get the variable "p" by itself in the equation:
19 = 4p - 5 Add 5 on both sides
19 + 5 = 4p - 5 + 5
24 = 4p Divide 4 on both sides to get "p" by itself
6 = p Your answer is B
PROOF
19 = 4p - 5 Substitute/plug in 6 into "p" since p = 6
19 = 4(6) - 5
19 = 24 - 5
19 = 19
