tolong dong kk besok mau di kumpul.

a) 3x-4/x+1 = 5-(3x+1/x+1)
3x-4 = 5-(3x+1/x+1)×(x+1)
3x-4 = 5-3x+1
3x+3x = 5+1+4
6x = 10
x = 10/6
x = 5/3
x = 1⅔

b) 2x+5-4x >= 2x-5(x-2)
2x+5-4x >= 2x-5x+10
-2x+5 >= -3x+10
-2x+3x >= 10-5
x >= 5

c) 2 <= 3x-5/5 <= 5
2×5 <= 3x-5 <= 5×5
10 <= 3x-5 <= 25
10+5 <= 3x <= 25+5
15 <= 3x <= 30
15/3 <= x <= 30/3
5 <= x <= 10
