Answer:
Step-by-step explanation:
Given the equation px - 8 = 5x + 9, we can only find the value of p when x = 4.
To get p, we will substitute x = 4 into the expression as shown:
p(4)-8 = 5(4)+9
4p - 8 = 20+9
4p - 8 = 29
4p = 29+8
4p = 37
p = 37/4
p = 9 1/4
Hence the value of p so that x = 4 is the only solution is 9 1/4
