Matematika SMP Kelas VII

(1/2) . x + 1/3 = 5
(1/2) . x = 5 - 1/3
(1/2) . x = 15/3 - 1/3
x = 2 . 14/3
x = 28/3

-----------------------------------

1/(2x) + 1/3 = 5
1/(2x) = 5 - 1/3
1/(2x) = 15/3 - 1/3
1/(2x) = 14/3
2x = 3/14
x = 3/28

1/2x + 1/3 = 5 (dikali 6)

3x + 2 = 30
3x = 30 - 2
3x = 28
x = 28/3
x = 9,33
