The answer is the sum of three times a number and six, divided by the difference of seven times a number and nine.
The phrase is(3p+6)/(7p-9)
Let’s describe each factor:
3p is three times a number
7p is seven times a number
3p+6 is the sum of three times a number and six
7p-9 is the difference of seven times the number and nine
The last two factors are divided, so
(3p+6)/(7p-9) is the sum of three times a number and six, divided by the difference of seven times the number and nine.
I hope this helped and have a nice day!
