is this n=1 ??
This might be n-1.
2/3(9n-6)+4(n-1)
2/3 is multiplying by both 9n & 6 and in the same way the 4 is multiplying by n & 1.
So,
2/3(9n)-2/3(6)+4n-4
3 cancelled 9 by 3 and then the remaining 3 is multiplied by 2 resulted 6.
3 cancelled 6 by 2 and then the remaining 2 is multiplied by 2 resulted 4.
6n-4+4n-4
This is simple now
Answer = 10n-8
OR
This may be 2/3(9n-6)+4 while n=1
in this case
2/3[9(1)-6]+4
means
2/3(9-6)+4
2/3(3)+4
....................2*3 = 6.
....................6/3 = 2.
2+4

1) (9n-6), so plug in 1 and it becomes
(9-6) = 3
2) 2/3 * 3 = 2
3) 2 + 4 = 6
Answer = 6

10n-6=4
add 6 to both sides,
10n=10
n=1
Tada! Hope I answered your question
