Pembahasan :
(x - 1)/2 + (x/3) = (3x + 1)/5
Kali 30 kedua ruas, sehinga...
15(x - 1) + 10(x) = 6(3x + 1)
15x - 15 + 10x = 18x + 6
18x - 15x - 10x = -15 - 6
-7x = -21
x = 3
Verified answer
(x-1)/2 + x/3 = (3x+1)/5(3(x-1) + 2x )/6 = (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 = 21 : 7
x = 3
Opsi C
Semoga berguna +_+
