Answer:
x=8 and p=17/3
Step-by-step explanation:
Write in the same denominator, in this case, 15 is the LCD.
[3(4-3x)+5(7-x)+5(13)]/15 = 0
(12-9x+35-5x+65)/15 = 0
(12+35+65-9x-5x)/15 = 0
(112-14x)/15 = 0
112-14x = 0
112 = 14x
112/14 = x
8 = x
substitute x in 3p - 2x +1 = 0 to find p.
3p - 2(8)+1 = 0
3p = 17
p = 17/3 or 5 2/3.
