Tentukan nilai x yang memenuhi persamaan 1/3x-1/2=4

1/3 x - 1/2 = 4
-------------------- kedua ruas dikali 6
2x - 3 = 24
2x = 24 + 3
2x = 27
x = 27/2
x = 13 1/2

jika pertanyaannya 1 / (3x - 1/2) = 4
1/(3x-1/2) = 4
1 = 4(3x - 1/2)
1 = 12x - 2
12x = 1 + 2
12x = 3
x = 3/12
x = 1/4

jika 1/3x - 1/2 = 4
(2-3x)/6x = 4
2 - 3x = 24x
2 = 24x + 3x
2 = 27x
x = 2/27
