b). $\frac{t-1}{2}$ - $\frac{t}{5}$ ≥2
c). $\frac{x-2}{3}$ - $\frac{x}{4}$ > 0,5
d). $\frac{-2x+1}{3}$ ≥ $\frac{-3x}{2}$
Va rooog ajutati-ma repede.

Answer 1

-(3x+1)/2<1
-3x-1<2
-3x<3
x>-1

(t-1)/2-t/5≥2
5(t-1)-2t≥20
3t≥25
t≥25/3

(x-2)/3-x/4>1/2
4(x-2)-3x>6
x>14

(-2x+1)/3≥-3x/2
-2x+1≥-9x/2
-4x+2≥-9x
x≥-2/5
