You cannot combine any the terms because x and y are two different variables. that is the most simplified you can get.
5x = 2x + 9, where 5x > 0 and 2x + 9 > 0 ;
Then, 3x = 9 ;
Then, x = 3 ;
Verify : 5 × 3 = 2 × 3 + 9 ;correct !
5 × 3 > 0 ; correct !
2 × 3 + 9 > 0; correct !

Answer:
an = 65 + 5
a1 = 65
Step-by-step explanation:
If the begining value is 65, then a1 has to be itL
a1 = 65
Then, if this amount increased every minute then 5 has to be added to this value each time:
an = 65 + 5
But this means that 5 is added to 65 every time with no increase, so the five must me multiplied by the n value:
an = 65 + 5
a2 = 65 + 10 = 75
But this value should be 70 because it is the first point after 65 so it should be +5 not +10
To do this we can simply subtract one from the n value that is being multiplied by 5:
an = 65 + 5
Which is the recursive rule!

First you multiply 1/2 with 2 and 1 with n^2+3n
After doing so you got n^2+3n/2n^2
Factor n^2+3n but keep 2n^2still
n(n+3)/2n^2.
Finally Simply n
You got
n+3/2n
