Question

1/2 [3n-4] = 2/3 [3n-6]
n=....

Answer 1

3/2n -2 = 2n - 4
3/2n - 2n = -4 +2
3/2n - 4/2n = -2
-1/2n = -2
n= -2 / - 0,5
n= 4

pembuktian :
1/2 (3(4) - 4) = 2/3 (3(4) - 6)
1/2 (12 - 4) = 2/3 (12-6)
1/2 (8) = 2/3 (6)
4 = 4

Answer 2

1/2 [3n-4] = 2/3 [3n-6]
3/2n - 2 = 2n - 4
3/2n - 2n = - 4 + 2
- 1/2n = - 2
n = (-2) : (- 1/2)
n = 4
jadi nilai n adalah 4
