Persamaan( x-1)/2+x/3=(3x+1)/5 mempunyai penyelesaian... A. x=1 B. x=2 C. x=3 D. x=4 E. x=5 tolong dijawab menggunakan cara dengan jelas:))

(x - 1)/2 + x/3 = (3x + 1)/5
[3(x - 1) + 2(x)] / 2(3) = (3x + 1)/5
(3x - 3 + 2x)/6 = (3x + 1)/5
(5x - 3)/6 = (3x + 1)/5
5(5x - 3) = 6(3x + 1)
25x - 15 = 18x + 6
25x - 18x = 6 + 15
7x = 21
x = 3

Cara lain
(x - 1)/2 + x/3 = (3x + 1)/5 =====> kali 30 (KpK dari 2, 3, 5)
30 . (x - 1)/2 + 30 . x/3 = 30 . (3x + 1)/5
15(x - 1) + 10x = 6(3x + 1)
15x - 15 + 10x = 18x + 6
25x - 18x = 6 + 15
7x = 21
x = 3
