Answer:
P = -30
Step-by-step explanation:
first, you need to move the virable to one side:
3/4P - 4/5P = 3/2
second, you make the denominator the same:
15/20P - 16/20P = 3/2
-1/20P = 3/2
third, you will divide it both side of -1/20:
-1/20 -:- -1/20P = 3/2 -:- -1/20
P = 3/2 x -20/1
P = -60/2
P = -30
