Answer:
8/3 or 2.67 in decimal
Hope this helps :)
Step-by-step explanation:
9n + 1 = 6n + 9
bring the variables to one side
in this equation the variables are 9n and 6n
while bringing 6n to the left side it turns negative:
9n -6n +1 = 9
3n + 1 = 9
bring 1 to the other side
It turns positive while bringing to right side
3n = 9-1
3n = 8
bring 3 to the other side, becomes 1/3
n = 8*1/3
= 8/3
= 2.67
