Answer 1

Sper ca o sa-ti fie de ajutor!!!!!

Answer 2

x apartine N

a)(3x+2)/(2x+3)=4/3

Faci inmultirea mezilor si inmultirea extremilor:

3(3x+2)=4(2x+3)

9x+6=8x+12

9x-8x=12-6

x=6. care apartine lui N

b)1/(2x+4)<2/(6x+2)

Idem a):

6x+2<2(2x+4)

6x+2<4x+8

6x-4x<8-2

2x<6            | :2

x<3

x apartine (-infinit, 3) intersectat cu N={0,1,2}
