tentukan nilai n dari persamaan 1/2(4-n)-1/3(1+n)=1/4

Menentukan Nilai n

Soal
1/2(4-n) - 1/3(1+n) = 1/4
n = ...

Penyelesaian
1/2(4-n) - 1/3(1+n) = 1/4
2 - 1/2n - 1/3 + 1/3n = 1/4
6/3 - 1/3 - 1/2n + 1/3n = 1/4
5/3 - 5/6n = 1/4
5/6n = 5/3 - 1/4
5/6n = 20 - 3 / 12
5/6n = 17/12
n = 17/12 × 6/5
n = 102/60
n = 17/10
