Answer: see proof below
<u>Step-by-step explanation:</u>
Answer:
4n+(2n-9)
4n+2n-9
6n-9 =the total age
6n=9
divide by 6 both sides.
n=9/6
n=1.5 years.
substitute the value of n in the age of the father and the daughter.
Age of father=4×1.5
6years.
Age of Daughter = (2×1.5)-9
3-9
=-6 years
Total age
6-6=0
Number one would be 1.5 , 3 and number two would be 1.5 , 1
3(6x+1) I’m not sure but probably this could be right
