(x + 9)/2 - (2x-3)/2 = (3x + 4)/4
(x + 9) - (2x - 3)/2 = (3x + 4)/4
(x + 9 - 2x + 3)/2 = (3x + 4)/4
(-x + 12)/2 = (3x + 4)/4
-x + 12 = (3x + 4)/2 (dikali 2)
2(-x + 12) = 3x + 4
-2x + 24 = 3x + 4
24 - 4 = 3x + 2x
20 = 5x


x = 20/5
x = 4

Bukti :
(x + 9)/2 - (2x -3)/2 = (3x + 4)/4
(4 + 9)/2 - (2 × 4 - 3)/2 = (3 × 4 + 4)/4
13/2 - 5/2 = 16/4
8/2 = 4
4 = 4


Semoga membantu ^^
